Sega will be running a pricey viral ad campaign through Microsoft's Windows Live Messenger to promote its upcoming games: Sonic Rivals on the PSP and Sonic the Hedgehog on Xbox 360. One may notice that the PLAYSTATION 3 version of Sonic the Hedgehog is not mentioned. Just like Sonic and Silver pictured above, Sony and Microsoft are fierce rivals, and it appears that Microsoft wants no part in promoting Sony's next-gen platform. Of course, without a handheld gaming device from the Xbox folks (for now), it seems Redmond's empire is willing to litter your IM-ing experience with ads for the PSP Sonic.
Expect a full review of Sonic Rivals and a giveaway soon.
