X-E1 vs X-Pro1

You said you want to switch from Sony to Fuji because of the lack of lenses.... if that is the only reason, look carefully, Sigma is getting on this market and/or with adapters you can virtually get any lens you need/desire.

Now if you want to change for some others reasons, make it clear, which ones !

List your preferences on paper and make your choice.

As for the promotion, I wouldn't care, again look into it closely, I don't believe you can chose the second lens that easily, there should be a trick somewhere.

If I were you I wouldn't change, because even the X-E1 is too big for me and because the Nex-7 is a new camera, let pass at least 3 generations. It seems to me you should go out and take pictures instead of reading spec, you are on your way to be never satisfied.
