No idea what that means might have a new AF system, improved sensor and no doubt the new hot shoe, better EVF etc and a few more bits. It might not be (depending on price) a sure fire upgrade for some users.
I have enough equipment and with s/h bodies to sustain A mount for a good few years if required, but I'm certainly not going to invest in any exotic stuff.
I think that's the problem for Sony, users are nervous those that do stay will likely reign in or postpone any serious spending to see what happens.
If after this A77II release, there is very little activity (either in lenses or new bodies) I think that will be taken as a sign things are not looking good.
It is possible there might be another FF A mount body, but I can't see that doing much unless it's a very competitive offering. A99 is still £1800
Now is not the time to be investing in expensive Zeiss glass or higher end bodies! I'd be amazed if Sony are pulling in many new users
