Mario & Sonic at London Olympics sighted?

Mario & Sonic at the 2012 London Olympics is on the way, if leaked art is to be believed.
Two placeholder sleeves dug up at Sonic Stadiumshow logos for a new Olympics game and something called Sonic Generations – most likely the game that SEGA posted a teaser trailer for earlier this week.
If legitimate, it wouldn't come as too much of a surprise - a new Olympics title was hinted at last year by a Spanish SEGA rep.
When contacted by Eurogamer for a confirm/denial, a SEGA spokesperson replied "No comment I'm afraid."
This would be the third sports spin-off for the former platforming rivals, after getting involved at the Beijing games in 2007 and the Vancouver Winter Olympics in 2009. The former managed around 10 million sales while the latter netted a still-impressive six million.
