Hi The Kellyboy,
At this point in time, I'd think that price would have to be a significant consideration. Personally, I find the larger sensor pretty much a horizontal "upgrade". To get significantly better IQ, from what I've seen, you'd probably have to go to a 1" sensor. Feature-wise, the cameras are pretty close. Of course there's the FOV difference - if you tend to shoot wider, then the Q7 will probably fit your wants a bit better since the lens lineup is, at this time, pretty limited.
A good portion of your decision probably should be based on which lens(es) you plan to use most extensively. If you like the idea of a fast prime, then you might find the best deal in a Q + 01 kit if you can find one. You can also possibly get a Q + 01 and 02 kit for less than a Q7 + 02 kit, and if you decide that you want the larger sensor, then just get the Q7 body once the price drops.

I see that mtgal has made the points I was trying to get across while I was still typing. . .
