sony wants people to continue buying ps3s, obviously. The ps3 is likely making a profit, given the lack of pricedrop with the slim. Lots of companies kept supporting the ps2 when ps3 arrived and several big sony first party games were released shortly before ps3 dropped.
Source: Ps2 shipped an additional 50m consoles after ps3 released.

i am not saying to not support ps3 but as i mentioned instead of releasing all these 4 on ps3 (sly4, god of war, last of us and beyond two souls) they could release 3 of them on ps3 and for example last of us or god of war on ps4 . wouldn't that be a better plan ?

You're forgetting that these games have likely been in development for 2-3 years.

They've also already been announced for ps3.

All the art assets are ps3 level graphics.

It simply isn't feasible to put them on ps4. Just look at ff13. FF13 was going to be released on ps2. Was in development for a long time, then had to be redone. The entirety of the ff13 corruption stems from doing exactly what you are suggesting Sony do.
