Now, a 645D II with the latest/greatest, and better yet a non-cropped Medium Format sensor - that might be tasty, especially if it's priced the same as the original 645D or less, but then again you're taking about a $10,000 body + $4000 lenses to take the space of a $2500 FF body and the same lenses we can shoot on aps-c. It's not the same thing, doesn't sell to the same set of folks.

I agree, MF is a completely different thing altogether in my opinion. It's for studio pro work.
Just priced up a Nikon D800e with Nikon grip and 3x spare Nikon bats, an SB910 flash and the sort of lenses (4No.) I'd actually use and the total has come to a bit less than I've spent on Pentax APS-C cameras and lenses, flash etc.
I'm not running Pentax down here, they're seriously great cameras and lenses, it's more about me having selected the wrong gear through ignorance and buying too many lenses I never use. Same goes for tripods. Tried the mid-range stuff and it wasn't quite up to the job.
As someone coming out of the camera newbie stage I recommend anyone wanting to get into this just buys a fixed lens camera with full manual control that shoots RAW and a good PP package to learn on for two years. Then if you're still into it really research the hell out of the thing and go for the good stuff (but not too many lenses you don't need), because an awful lot of money is wasted on mid-range kit.
