I saw this too, and I nearly lost my mind.
At first, I was like, "This is cool, but they're just re-airing old clips and video." Then I saw that TOM 3.0, not the shitty moving face TOM, was reviewing Mass Effect 3 with all new dialog. I literally exclaimed "Holy Shit!" out loud. I then proceeded to watch as much of this as possible.
It was all like I remember it. The Absolution. TOM being even more cool given his leeway with language now. The classic musical promos (DON'T FEAR FAILURE). The good animes. Too bad SARA wasn't there. It was also great that they aired some episodes they never aired before, with more mature dialog.
We need this back. Kids need to see the "Dreams" promo again. They might not get it now, but it's sooo much better than the usual moral crap they hear all the time. We need this back and, as much as I don't like some stuff on Adult Swim, Toonami fits there. It was great while it lasted, but now I'm only sad that it was only a one-time thing.
Bang.
