1. 7D is hardly a wedding grade camera
Uhm, I didn't say anything about the 7D & weddings; I was talking about the X-Pro 1:
Right now, the X-Pro 1 is the smallest, least expensive, and sexiest camera with wedding-photographer grade image quality, and Fuji still has plenty of other tricks up their sleeves to roll out over the next year or so.
I certainly wouldn't use it as my only camera, but with the 3 lenses they're shipping at release I think most professionals would be perfectly comfortable shooting a wedding with the X-pro 1 and 18/35/60mm trio (and maybe an adapted Nokton for posed portraits). I'd want another body like a 5D with an ultrawide on it and maybe a zoom in the bag just in case, but that would pretty much do it for me.
2. There isn't the range of lens to shoot a wedding. Fujifilm will be a bit player for some time
AF lens options will be limited for another year or so perhaps... You can be sure that there are a lot of wedding/artistic/street/travel shooters out there without the dosh for a digital Leica M that own M glass that are looking very keenly at moving up to the X-pro 1. The best adapted mirrorless options up 'till now (pana, oly, sony, ricoh, etc.) have been OK but none of them feel or handle like a rangefinder like the Fuji does, and the image quality speaks for itsself. The fact that Fuji's AF lenses cost half as much as their Canon L or Sony/Zeiss counterparts will certainly push adoption as well.
