This uploaded video on YouTube is supposedly the leaked first footage from the God of War Collection. There's nothing specifically there to indicate that it actually is, but just the same, why don't you check it out and see for yourself?
Barring the less than superb audio, it's still a pretty good watch. The graphics, for one, as also looking more crisp than the original versions. God of War Collection includes the original game and the second sequel. It has also been reported that it will include the demo for the much-awaited God of War III.
