Sonic? In my Mario?

UK magazine Ngamer has posted an interesting tweet on Twitter this afternoon, making a rather bold claim that not only comes right out of the left field and has left us all a bit dazed and confused here at Nintendo Life Towers.

We should stress this is currently deep in the realms of rumour territory for now, with no confirmed word from Sega or Nintendo, so please take it with a rather large pinch of salt for the time being.

Here's the Tweet in question:

We've just had some shocking news from an inside source at Nintendo: Sonic will be a playable character in Mario Galaxy 2! Wha?

They sound about as surprised as we are! As always we'll keep you posted if the blue speedster and the world's favourite plumber do indeed join forces outside of the Olympics.
