Time to upgrade?

So, I definitely love my Incredible, but now that I have an early upgrade, I'm wondering whether I should.

If I'm going to do it, I'd like LTE, so I guess my choices are the Thunderbolt (apparently terrible battery life?) or the Charge (good reviews, but I really like HTC sense).

Should I hold out for a new phone over the summer or fall? Something from HTC with dual core proc might be nice.
