It does have the snow theme which hints it could come out around christmas. Is it possible it will come out this year?

I expect it to come out during spring when Gears of war 3 comes out and nothing sooner then that.

I thought it was said to be releasing next year?   So I would say slim to no chance of releasing this year. 

not at all likely, if anything it will be pushed back not moved forward.

No chance, a May release has apparently been pencilled in

May 2011 is rumored I think...

Highly unlikely to happen.

nope not with games like GT5 and LBP2 releasing this year.

both games should sell more than enough for sony.

It would be great if they released it this year but it would be smart to release it around the same time as Gears of War 3. I think having something to compete with Gears 3 in April of next year would be a good choice. Now I really think if it does have a chance to be released this year it will be in November. Killzone 3 looks pretty far along just from the recent stuff I've seen. Who knows, we will all find out come E3.

May 2011. But E3 is going to confirm the release date.
