At the GDC, Sony had broken news that developers and game companies may like to hear. Sony will "put their money where their mouth is" and match game developers budget in exchange for Playstation exclusivity. This can be good considering that Sony will let the devs control their game rather than giving Sony all the rights. It is also worth noting that Sony is not doing the "buy out" tactic that Microsoft did/does. Sony also says that "these games will not be considered a first-party publishing. Sony is not buying your product."
This is a very good idea on Sony's part. If they can get good games aboard, this plan may profit Sony and the game devs/companies. Hopefully Sony can get their hands on great games but it is uncertain if devs will be willing to sacrafice selling and making games cross-platform and making double profit, over for free money. Only time will tell if devs will go with this but I think some will.
