Im excited about the BR, however I dont trust it. I will be getting a PS3 and I would BR or not. Some people are using BR and an excuse why they wont buy one when infact the simple fact of larger disc will make the games better.(more space). I however question the bigger discs as they may be needed for PS3 format as it may take up more disc space but there was only a small % of PS2 games that actually used the entire DVD Disc.
Concerning Copy Protection, the federal law permits you to make 1 working back up of any media stored on a disc simply meaning that there will be ways around the protection. If games are using a large majority of the BR discs I will be renting them instead of download to see if I would even consider buying them.
