I don't know why anyone would think the PlayStation division would be going anywhere. They have been releasing New IPS and Exclusives every year. That is more than you could say for Nintendo and Microsoft, who are making a lot more money than Sony.
Nintendo and Microsoft have enough money to take chances and what chances do you see them making as of lately. I'm not talking about systems; 3D and the second screen were gambles and paid off for them. But when you mention Nintendo, your conversation will always have a Mario, Zelda or Pokémon game in it. Same with Microsoft, you think of Halo, Gears and Forza or what next shooter will they release next.
At least with Sony, you can expect the unexpected and different IPs, even if they decided to use the same characters of their existing IPs. They have some of the best Devs, which are not scared to move on from their old IPs and past them on to someone else.
I think the PlayStation division will be around, well past 2 years. If any company can bleed money and still offer a great offer on PlayStation Plus and so many rented(free) games, then they are not going anyway.
