What, not backwards compatible?

I was just reading up on the soon to be released Sony Play Station 4. ( some time by Xmas?)
and there not even going to try and make it backwards compatible. hmmmm. Major Hardward upgrade?
it looks like X-Box will be doing the same thing. 7 or 8 year run?
Doesn't matter to me. PS 3 is good for what I want.

oblivion and Skyrim.
