how long is a piece of string? - seriously though, dont hold your breath.
with all this info coming in about financial troubles at leica, wich i hope isnt true! - a new scope may be the last thing on there mind. no doubt they have been looking to replace it for a while now, to stay at the top of there tree, but i have yet to see any prototype as of yet.
if they are planning to bring a new one out, i will sell my APO 77 to a fellow BF member at a knock down price.....only 9 month old too!
