But second place is important isn't it? I think it's what gave MS the ability to secure the exclusive DLC, extra packs and exclusive bundles that they used to get for the 360, precisely because of the fact that they were ahead of the PS3 (as well as some money hats, I don't doubt that)
But if the PS3 is in second place, then it suddenly gives Sony more flex to able to secure those things from third parties, which would make the PS3 version the better choice for buying third party games, something which the 360 has enjoyed (and still does, just) for a long time. I think second place is important.
