If you were Sony you would want as much money out of the PS3 as possible. You want to have as many profitable units as possible. The PSP, Vita, PS3, are profitable right now for Sony. When the PS4 releases it will be selling mainly to people who already have a PS3. Those people will then buy a PS4 and possibly GT6 if they are a fan. This whole releasing AAA games late in the generation concept is very good for Sony because while the PS4 is selling well, so will all there other consoles that people were waiting for in the first place.
Some people are waiting for the price of the PS3 to drop. If they didn't want the PS3 at $399 then they won't want the PS4 at $399. So Sony's only option for that type of consumer is to eventually drop the price of the PS3 and watch millions more people jump on and continue buying games for it because it really does have some of the best games in the industry. The PS3 still has a long road ahead. Probably more than a ten year life cycle and I wouldn't be surprised to see PS3 outsell the PS4 for a couple of years.
