It's unclear but the screenshots are supposedly of an internal Verizon document which you wouldnt expect to mention GSM capability otherwise.
In any event, a world LTE phone should be a reality at some point. The next-gen Qualcomm chipsets and radios will have support for LTE, CDMA, and GSM. While most manufacturers will opt not to implement all the standards on a handset to save money, there is a market for a world phone that I expect someone will cater to.
