I agree 100% with Doug...full frame has a future, but it isn't the future...absolute image quality is a pretty small fraction of photography.

The top of the line crop cameras are really, really, really nice cameras and there is no reason why crop sensors won't continue to improve in quality with technological advances. Sure full frame may always have an absolute rendering advantage, but most people - even publishers and clients - aren't going to notice or care.

I'd buy lenses that you need now, not lenses that you may need one day later down the line. Besides, a lot of the old film lenses are pushed pretty hard by the new digital sensors - full frame manufacturers are going to have to redesign a lot of full frame lenses in order to keep up with extremely resolution-hungry sensors...Why buy twice?

You need FAST and high quality lenses. Zooms that cover about 28-100mm, 100-200, and a nifty 50 (50mm f/1.8, because it's awesome and dirt cheap). Those are 35mm equivalents. I know a wedding photographer who has a full frame 5d, a 28 prime and a 50 prime, and shoots EVERYTHING with them. His only flash is a ring flash from his glamour/fashion magazine days. In short, you'll be a step ahead as far as gear but a few years in the trenches is more important than fancy kit...
