Both BioShock and Splinter Cell Conviction (the suspected title for the post-Double Agent iteration) will be console-exclusive to the Xbox 360; BioShock will still be coming to the PC, while Splinter Cell can still be released for the PC and various portable console (DS, PSP). BioShock publisher Take-Two will also be providing "exclusive access to two downloadable, epic episodes of Grand Theft Auto IV via Xbox Live, each with hours of entirely new gameplay ."

Ubisoft's Splinter Cell Conviction is the title found during their "accidental" leak earlier this month. The exclusivity of BioShock was predicted by GameSpot back in January after developer Irrational was bought by Take Two.

The GTA IV episodes are a "complete exclusive," according to Scott Henson, Director of the Game Development Group at Microsoft, and will not showing up on the PlayStation 3 download service. The episodes will be available a few months after the release of Grand Theft Auto IV on October 17 and 19 in US and Europe, respectively. Microsoft hinted at exclusive GTA IV content as early as July.

While BioShock may not affect the mass audience, the loss of Splinter Cell and some exclusive GTA IV content could hurt the PlayStation 3's image in North America and Europe. Then again, Sony does have Metal Gear Solid 4 to satiate its consumers, but what are the long-term ramifications of Microsoft's exclusive deals?
