"[BigDownload was] a little worried when [they] saw the big Splinter Cell Conviction banner at the LA Convention Center this week with just an Xbox 360 logo. [They] thought for a moment that Sam Fisher's latest spy adventure was going to bypass the PC. Thankfully Ubisoft's E3 2009 press conference on Monday put that thought to rest."
Splinter Cell: Conviction will be coming to both the PC and Xbox 360; it was previously believed that it was an Xbox 360 exclusive.
