I honestly can't be bothered to stand in line or be squashed by a horde of eager geeks, only to look at something that's going to be in my living room in the next couple of months. What matters is the quality of the games on offer, and for that you can simply watch HD YouTube clips behind your own PC to get an idea of what's coming.
But I digress, I understand why they're doing it and it's not a bad thing.
