Super Canon newb question...

I was reading that the EF-S lenses will NOT mount to the full frame bodies.. the mount is physically smaller...

Well... Will the EF lenses mount on the crop bodies???

EF lens will mount on crop bodies perfectly fine, but the specified focal length will actually be 1.6x of that due to the crop factor.

For example, a 50mm would become something along the lines of a 85.

Yes.

EF lenses will fit on crops.

Correct

Not correct. The focal length does not change at all.

Crop factor applies to bodies, not lenses. An APS-C body will crop the image circle formed by a lens more than a full frame body. The effect is that the image captured by an APS-C body is the same as that captured by a FF body with a lens 1.6x as long.

Unless formats (and certainly not just lens mounts) are being compared, crop factor is a confusing irrelevancy.

Alright, sweet. I thought so.

And thanks for the bit about crop factors. I did know that, I'm just new to canons, and got confused about the physical mount thing. This makes me feel much better!
