This is the high-res MGS4 trailer from TGS in its entirety (save for the PS3 logo at the very beginning). It's 640x360 with good clarity, and you can definitely see much more details in this one. The only downside is that the audio has been downsampled to 44 KHz from 48 KHz in the original trailer released on the official MGS4 site.
