Default How much longer do you think carriers will offer the G2?

After seeing, and being disappointed by, the G3; I'm just curious as to how long you guys think the carriers will continue to offer the G2. Most notably T-Mobile. I have decided on the G2 over the G3, but want to see if the price will drop after the G3 is released. However, I don't want to wait too long and lose out on picking the phone up through the carrier. What do you guys think? Will the G2 be offered alongside the G3 for a couple of months? Thanks.
