It has the exact same interface as the motorola droid then.
You really do not want that interface, it is annoying like you cannot imagine. My cousin has the Droid. Good thing the phone is running Android and you can customize it.
It really doesn't have anything too impressive in that vid though. Just basic features that pretty much any old android phone will have. It still looks pretty impressive, but so do most touchscreen phones when you really know the interface and go through them fast like that.
I doubt they will make that exact phone on GSM since 4G is its biggest attraction. HTC will most likely have a similar GSM phone though. Expect it to cost a fortune though. I really think the nexus one is the best buy phone on the market right now. $529 with no contract, like $129 with a contract, and I don't think there is anything as powerful as it is.
