According to Gamestop, the release date is 3/9/10, is that confirmed? I mean i know most baseball games are released around Feb-March, but was wondering if that was the actual release date.

Sounds like a pretty solid date considering the previous two games were released on the 3rd and 4th of March. 

yea around march like diablerie stated should be right.

you mind linking like to learn more about the any new features it getting.

i got the date off of gamestop, which is why i was wondering if sony stated anything about the game

Googling doesn't seem to turn any official announcements up, so it's most likely just a placeholder date.

^ yes, but its almost around march.
i wouldn't preorder until it's official.

im anxious to see who they put on the cover, a pitcher would be interesting

Looking back at past 2 release dates:
09 = Tuesday, March 3rd, 2009
08 = Tuesday, March 4th, 2009

From this, I would predict Tuesday, March 2nd, 2009.
