What adapter to use for legacy on FF Nex when it comes?

I have just found that i cannot get my Nex-7 with adapter and Minolta 50mm 1.4 in the pocket of my new coat.

Am i correct in thinking that when/if there is a FF Nex i will be able to put the legacy lenses on the Nex-7 with a much smaller adapter??

Though it would probably be cheaper to buy a new coat with bigger pockets.
