Sony US has confirmed boxart recently seen flying around the web is indeed the official, finished product. It looks pretty nice too.
The US Playststion Blog has also confirmed the game's rating: "We're also able to confirm Heavy Rain's final ESRB rating has come in at a strong M for Blood, Intense Violence, Nudity, Sexual Content, Strong Language and Use of Drugs.
"And for those of you who have asked, the content is exactly the same as what's being released in all our territories, so you'll get to enjoy it exactly as Quantic Dream intended."
Sony UK recently confirmed that PS3 exclusive Heavy Rain will be released in the UK on Friday, February 26, just like we said it would.
