Just the beginning, can't wait for the meltdowns when they shut down the store and ability to download games in the future. I remember some dude that bought all digital games was trying to tell me the PS3/360 would never disable the ability to download games they have bought XD.
If they prevent PS3 oowners from playing their PS3 games purchased on the PS Store, they will be implicitely giving the OK to pirate the games and play them on a PC with an emulator.
I have tons of PS3 games, many of which I have yet to play. I'm expecting to be able to play them all (disc + digital), forever or for at least as long as my second PS3 is working. If I decide to use an emulator on my PC, so be it.
If they plan is to take away the ability to play games we bought, we are we putting money into consoles and games in the first place?
