Verizon just got the 7750 not to long ago. I believe its only the 6750 and the 7750 for now, haven't heard of any other plans. I have a verizon cell phone and use my company issued BB with TMO.
Most likely all you'll see for CDMA networks for now are the BB 6750/7750 do to the CDMA chip set and processor size/configuration the form factor of say a 72xx case is not an option at the moment for new product.
