You really think there's even a 5 percent chance of BC? And I said that to people about PS2/PS3 compatibility (just get a/keep your PS2) and I was told I was nuts. I still don't understand it. I have a PS2. I don't play it nearly as often as I do my PS3, but I still do sometimes. If the PS4 comes out this year, I figure I'll get one in 2015 or '16. My PS3 will keep me highly entertained, especially since I seriously doubt PS3 releases will just stop when the new console comes out. They sure didn't with the PS2 - see
this? Yeah, that's a game that came out 3 months ago.
So the sky is not falling. Even if they do that rumored "always have to be online" thing so as to neuter the secondhand games market.
