I think the Thunderbolt not coming out out with dual core/higher res screen actually bodes well for Sprint. Obviously, HTC will not let Motorola, LG and Samsung steal the all spotlight for too much longer with their "super phones". Verizon will have their Iphone so why not continue with Sprint where there is less competition.
I hope HTC announces their new line in Feb/March which includes the EVO 2 coming for Sprint.All they need to do is release GB in March and I'll be good until the June/July
