It really does depend on the speed of the subject and how you pan with it .

I have just contacted Tamron UK about the UK release of the lens and they have told me it will be January 17th for Canon Mount!!!!! - this is the same date as the US release so I am not sure if they have got it right. First I have heard about a UK date so I would be a bit skeptical as none of the UK Tamron dealers have got a release date up yet as far as I know.
EDIT: I see Park Cameras are saying the Canon mount ones are expected 17th January so maybe it is correct.

I see Calumet have it priced at 949 although I am certain this will come down after the early adopters have got theirs and stock becomes widely available.

Not so good here in the USA at least for me. I placed an order with Adorama on Jan 9 and received an email an hour or 2 later saying it was back ordered. I called BHphoto today, whose website still says Jan 17 and they checked with Tamron after I told them about Adorama. Looks like BH and Adorama sold out of the intial shipment and there is no new date on the next.

The cynic in me wonders if they are waiting to see if the first batch are usable before they make the second

I would say can be sold rather than is any use.

naw, they'll sell quickly, it's just the possible aftermath that will hold back future production

For the US, there might be a few Canon orders that get the first batch still expected Jan 17 - but I've been told Nikon mount and Sony mount have both been moved back...no official date yet given. I received notice from B&H that my Sony mount order which originally listed Jan 17 is now open-ended with no known date. Oh well - I sort of expected that to happen! Some Nikon mount folks I know have also received delay e-mails from B&H.

Lens as been shipped in the states, I have seen a few shots from a US guy on another web site and they look very mediocre - this lens always seemed to good to be true and it looks as if it is turning out that way, early days yet though.
BTW I see WEX has it in stock at 949.

Like most if not all zoom lenses, its long distance (>20m) performance seems to diminish somewhat. This is a physical limitation of zooms due to the large number of elements they comprise of.

Will likely have one in my hands tomorrow and will test it and compare it with:
1. Sigma 50-500mm OS (very sharp copy)
2. Sigma 500mm 4.5 (ditto)
3. Nikon 80-400mm (new model)
4. Sigma 120-300mm sport + 2x TC

Lets hope the user did something wrong or it was back/front focusing. I'd really like this lens to be a good surprise because I need more reach and I can't afford canon big whites (600mm,500mm,300mm I/II...)

There are far too many variables that will contribute to how the photos will turn out at those focal lengths to draw assumptions from one or two people's first shots. Light is crucial, atmospheric interference is always a consideration, the shooter's skill of course accounts for something, camera back or front focus issues, wrong settings, and so on. I'd wait until some highly skilled wildlife shooters, in good light conditions, and a lot more shooters' samples, start coming along before drawing a final conclusion on the lens' performance.

Sounds like you've read Ken Rowckwells article on lens sharpness.

Some decent user reviews coming from good photographers in the States - the consensus thus far is that the Tammy at 600mm is certainly better than the 100-400 + 1.4x tc (560/f8). Several folk have also stated that it is a lot better on a full frame (5D3) than on a crop Camera like the 7D. Still early days yet thought

One of the first tests in the UK, I think!

For the length and cost it holds well compared to:
Nikon D5200 + 50-500mm OS (very sharp copy, compared well to the 120-300mm sport + 2x DG)
Nikon D800e + Sigma 500mm + Kenko 1.4x (very sharp copy, as sharp as the Nikon 500mm VR I sold after I bought the Sigma)

Considering that the 7D is the weakest camera from the three and most people say that it is much better on the 70D and the 5DIII, I have great expectations with those cameras and the Nikon sensors (when the Nikon version is released).

The stabilization is good and the AF is fast and locks easily even in the terrible light we have today

Overall very happy for the price and even considering getting a 70D to play with it until the Nikon version is released.

Good comparison shots Micloi! How far away were the shots taken? Nice to see that the 150-600mm holds up well against the prime. Have you tried shots from a longer distance?

Added a few birds from my garden:

For the bad light and the high ISO capabilities of the 7D I am happy with these

Overcast
All at f7.1, ISO800 and speeds between 1/80th and 1/160th handheld

Maybe 7-8 meters away.
Light is not good enough for distant shots, will wait for a sunny day
