SOCOM 4 pushed to 2011. States "additional features" as the reason

If you haven't already heard, SOCOM 4 has been officially pushed to a 2011 release window. Which, by the way, is a mighty big window, so hopefully that'll be narrowed down soon.

What I find really interesting is this paragraph:

SCEA's senior corporate communications director, Patrick Seybold, told Joystiq, "We can confirm that SOCOM 4 will be released in 2011. The team is focusing on additional features which will help to deliver the most compelling and immersion SOCOM experience yet. Please look out for further updates and announcements over the coming months."

I wonder what "additional features" is referring to. A co-op mode? More maps? More single player levels? Who really knows. But they state that we'll be getting more details within the next few months so hopefully we don't have to wait to long to at least find out what we have to look forward to in 2011.
