Don't sell the 7D. Save up longer and keep two bodies. That way, you'll have a backup body if one needs repair. You'll also get to take advantage of the 7D's 8fps burst if shooting fast action and the 1.6x crop factor if you need more reach out of your lenses.
I may end up keeping the 7D anyway, not having much luck selling it. I did think about having two bodies, but selling made more sense to me at least financially.
