Well, I belive that the new format (at least one of them) will replace DVD pretty soon (in the next 5 years). The quality certainly is superior, though I hat it that DVD didn't have its full potential realized (only ten years on the market).

Personally I won't be purchasing any new formats until the format war is over AND the prizes drop significantly. I agree with trevor, that the gamers will probably play a huge part in deciding the outcome of this game.
