I am more concerned about what this idea may lead to, I mean its no big deal if its just the already released games... its when they start to tailor games they release specifically to support this exploitation.
Can almost see it now, low quality or small sized cutscenes in the game and a week later a DvD/BluRay of high quality cutscenes complete with a guide / installation package to insert the quality ones into your game.
... can even see the slogan: " Buy the cutscenes and get the complete gaming experience ( music and audio packs also available, each track sold seperately , subject to terms and conditions ) "
Ah well, its not like these days gamers will be bothered... they will simply open thier wallets even more, and take this new exploitation just as easily as they have accepted all the others.
