There has been a new site up with a Countdown clock counting down to Monday April 27 at 9 P.M. EST

The site's address is tu4ar.com

Now this is where the MvC2 speculation begins...

One clue is that there is a big 2 in the background...However the biggest clue is the url...

tu4ar could be an acronym for Take You For A Ride

Which as many know is the phrase sang in the MvC2 Select screen

This in conjunction with the ESRB rating and Achievements could mean it's coming out...

Lets discuss this...Also I got this from an article on Kotaku...
