When reached to confirm or deny it, Capcom has said that it won’t
make any statements based on rumors. The fact that they didn’t deny the
rumor (which they could’ve easily done if it was), is quite telling.
UPDATE (January 27th, 2013):Resident Evil: Revelations has
been officially confirmed for home consoles and PC. It will go on sale
on May 21 in the U.S., and May 24 in Europe.
