I wouldn't write the Galaxy off just yet, wait until it comes out. Hardware-wise (especially GPU) the thing looks to be an absolute beast. If the specs are correct, the SGX 540 GPU is supposedly at least 2x the speed of the SGX 530 - the Hummingbird SOC offers a strong CPU with a wickedly strong GPU to back it up.
EDIT: And remember that until the DROID series, Motorola phones of late were rather crappy.
Don't you think it is a little premature to claim the phone can be rooted, but has an encrypted bootload from a couple of tweets? I'm not claiming it is going to be easy, but clearly Steven hasn't gotten far enough along to start speculating - especially someone other than Steven.
