I guess the big question is, when A7 comes out, will the A6 users have to pay full price to convert over? Or will we gat an upgrade price?

If it's just a matter of an upgrade, get the A6 now and don't worry about A7... A7 is still a ways away, and procrastination won't get any project started or finished.

And if it's a matter of having to buy A7 new (no upgrade) get A6 now and dont worry about A7, it's still a ways away.
