as a fuji x-pro1 user let me refer you to this forum..
http://www.fujix-forum.com/
i'm sure you will find some comparisons there.
I believe their major difference is the AF speed. if the xe-1 is as good as the x-pro1 after firmware updates then is ok as long as you dont do any sports/bird/fast-moving objects photograpy. other than that its great.
Also the viewfinder is better in XE-2.
but again, check in the fuji x forum and you will find answers there
