your guess is as good as mine as how official this is(i think its fake,but i have been wrong before)...i do know that the MGS film had been on the cards for awhile,and even that Christian Bale was 'rumoured' to be in it(well,i think it was between him and Hugh Jackman)
here is the poster
it lists Daniel Craigs name at the top,and first...which leads me to believe it may be bollocks,surely Bale would be playing Snake..(ie The Star),so be first listed,right?
story is here
http://www.ps3center.net/news/3230/metal-gear-solid-movie-poster-found-at-sony-pictures/July 2011 release-for starters,Daniel Craig has Bond 23 out in 2011,and they always take an age and a lot of work to do...and Christian Bale has the new Batman and Terminator films out due 2011-2012..so he is gonna be busy also
and one to top it off...two British Actors??...nah,Hollywood wouldn't let that happen,LOL
The Poster is definetly a mock up i reckon,no doubt..i could of done a better poster myself...but whether its there for concrete plans for the movie i dunno
off topic
Reign of fire was on TV the other day,it was better that time around than when i first watched it all those years ago
