[Minolta] Opinions Sought on Nex-7

I currently have both the 7D and the a700, as well as a wide array of Minolta 
(and other brand) lenses.  But I'm getting weary of carrying around all that 
heavy equipment and am now thinking of selling my gear and getting one of the 
newer mirrorless systems.  Having been a Minolta user since the late 1960's, 
I'm naturally drawn to the NEX-7, but the specs on the yet to be released 
Fujifilm X-Pro 1 look pretty amazing, too.  Any thoughts on these cameras, pro 
or con?
