Johns question is very important.
Well, it seems you already have that accounted for.
Here is a thought; the A77II properly setup and operated is one of the BEST sports cameras on the market.
It's autofocus is blazing fast... faster than the A99. And it's frame rate is among the best available. Now the high ISO noise performance can't touch the A99... but the A99 replacement is supposed to have an improved version of the A77II's autofocus module.
There has been VERY little news of the A99 replacement release date. And while the A99 is TRULY a great camera, the update will be even better.
The A77II will be about 35% the price of that new replacement. And while it IS an EXTREMELY capable APS-C camera, there is no doubt that the Sony full frame A mount will be better suited for landscape and macro photography.
IF the A99II gets the A77II autofocus module and a decent burst rate, then that will make it VERY attractive. But if you can't wait until the spring or summer, then the A77II might be the way to go because it is a much better sports shooter than the A99.
By the way; image quality from both existing cameras is excellent, with the edge going to the full frame A99.
So to sum things up; if sports shooting (including wildlife photography) is the most important way you plan to use your new camera, then if the new A99II has the Sony 4D autofocus module then you can wait for it or buy the A77II now.
Either way you won't lose.
