Well, I am going out on a limb here and predicting that Verizon won't get the iPhone in 2011. I don't think that they will get it until their 4G LTE footprint is large enough (2013?). There are too many disadvantages to CDMA (slow speed, lack of concurrent voice/data). Apple would be going backwards if they supported CDMA.
The speed is fine and can still be upgraded (but I don't think they will). Simultaneous voice & data is also available.
These disadvantages to CDMA are a bug that AT&T has put in all it's user's ear. 92M ppl on Verizon right now know it's not true and issues like voice+data are already resolved if Verizon and Apple decide to.
