IMO this could be good. Microsoft needs to leverage windows PC as their primary gaming source before it begins to focus on a Multi-Microsoft platform presence. Basically, hey these wide range of games can be played either on the PC, on the XBOX, or on your tablet/phone, whichever you prefer. Sure super high end might focus on the PC/XBOX but there are plenty if not more games that could be played on all devices. This is also perhaps one the pillars that _might_ actually make their windows phones viable.
Nintendo can't certainly do this, and SONY can only partialy do this.
