IPhone 5, Droid Bionic, or htc Thunderbolt?

Im eligible for my 2 year upgrade and am wondering which phone to get. I live in lansing which is getting 4g starting june 16th so a 4g phone would be cool, however iv heard that the thunderbolt has terrible battery life. That makes me think that i should wait for the bionic or the iphone 5. The problem with waiting is verizon's tiered data plans, which are supposed to come out soon. Is the bionic or iphone 5 (which i know is unlikely to have 4g) worth signing up for tiered data?
