The folks at GameTrailers.com have been kind enough to post the E3 Metal Gear Solid 4 trailer in HD. It's worth a look if you haven't seen it. There's no gameplay footage, naturally, which renders any judgment premature. Still, it's hard not to be impressed on many levels. I don't think I've ever seen a shaky-cam effect done right by a computer before, even though they've been trying since Doom. The physics of the helicopters and bipedal robots seem like a step forward. They've even made Raiden cool.
The trailer ends by promising a 2007 ship date, which means there's no reason to spend the money on a PS3 this calendar year. Prove me wrong, Sony.
