Several points:
A. We are still over two months away from the console launch, plus whatever amount of time it takes for various additional titles to launch. A lot can happen, both good and bad, in two months.
B. It seems some people on these forums are expecting next-gen consoles to be huge steps, graphically, over what was previously capable on a system. The problem with this expectation is that there are several aspects to video games, and graphics is only one of them. There's also sound, control, physics, gameplay, replayability, and simple fun factor. The only way we can see games right now is through screenshots (which have the potential to capture 100% of the quality of the graphics of only one frame), and videos (which, due to the nature of the internet and web hosting, are of much lower quality than the game they are portraying). Video has the capability to show a little of the sound and physics, but nowhere near what the game can offer. Neither medium shows what the game is truly like, how it feels to play it, how much fun it really is. In effect, we're looking through a small fogged window into a potentially tremendous world. Some of us have faith (for lack of a better word) that we will be rewarded come launch day.
In the end, it all comes down to this: what do you look for in a new system? Personally, I want to play Saints Row and see cars and bodies go flying. I want to play Project Gotham Racing and marvel at the hundreds of spectators lining the raceways and the photorealistic buildings whooshing past. I want to play Kameo and roll through hundreds of enemies at a time. I want to play Elder Scrolls: Oblivion and immerse myself in an alternate world filled with details that rival the best fantasy novels written. But none of this is possible right now without the Xbox 360.
It seems like all the doubters ("that looks like shit", "xbox 1.5", "doesn't look next-gen") are simply trying to convince themselves that they shouldn't purchase it. That's fine; it's your money. But don't try to make us ones that are sold on it out to be blind, or mindless fanbois, or deluded.
By the way, this may come off more intense than I intended. I'm simply looking forward to the launch, and I'm getting (understandably?) tired of the negative comments here and elsewhere.
