Why? The EV-DO modem is plenty fast and requires no user intervention whatsoever. WiFi in this case would simply add more user configuration with negligible benefits (you're downloading BOOKS, not YouTube videos).

And why would GSM/CDMA matter at all? It's not as if you're paying for the service...

GSM would allow it to be used in markets without EVDO, although Amazon would need to figure out some kind of roaming agreement, flatrate data pricing, etc.

I use my Kindles (K1 and DX, I've seen other people with K2...I'll probably buy one myself for completeness) here in Afghanistan, and am probably going to set up a semi-pirate 1xRTT network, as USB gets old fast. The K1 only does EVDO (for which BTS gear is expensive), but the K2/DX do 1xRTT, so you can hack firmware on some of the consumer femtocells to remove GPS checks or spoof GPS.

Amazon doesn't need to figure out any roaming deals. i have my own country-wide (and Brazil is pretty wide) data plan and adding one more device would be trivial.

As for the wi-fi, I have a big library sitting on my network and it would not fit in a Kindle.
