I've been thinking about the ps4's lack of backwards compatability and how it might be problematic during the transition from ps3 to ps4. It's obvious that Sony's plan is a giaki streaming service solution, but this sounds like it wont be ready in time (at least during the first part of the transition when it could be the most important).
So I had an idea for a PS3/PS4 CROSS BUY PROGRAM
During the transition many games will be made for both ps3 and ps4. Watch dogs, call of duty, destiny, etc. The largest game publishers will be making cross gen games for sure, because the low install base of ps4 will not be profitable enough (plus why leave potential customers out?)
So why not put both ps3/4 games on one disc and offer a sort of cross buy program. This minimizes the problem of backward compat for purchasers of at least the newest ps3 games, and would really helps software sales of ps4 games imo.
Think about it. It's not like many sales would be potentially lost (who buys a game then gets an upgraded version of the same game later?). In fact; a cross buy system like this could encourage gamers from holding off on getting games at the end of the generation (many skip buying games toward the end of a generation because they are waiting for the better version on the next system and saving their money for the newest best thing). Publishers would win because they get the ps3/ps4 base to sell games to still (somewhat combines base for game sales during transition) and gamers would have a special incentive to keeping getting games for their ps3s because they'd be building up a library of ps4 games (adds a special incentive to buy ps4 too).
Any reason why something like this wouldn't work?
