While I'd agree with common perception that this isn't the biggest story of the year by any means I think it has a particular significance for us gamers. In recent times we've really begun to notice the importance of big business with respect to gaming. More and more often we see small tributary business' being bought up by the larger companies. Intel bought Havok and not to be outdone AMD swooped for ATi. Presumably this should imply more competition and better prices, however I do wonder, is having such a duopoly competitive for gamers or simply competitive for the companies themselves?
