How long will these games remain exclusive.

L4D no, I don't think any company has gone multiplatform with a collection. If 3 was it'd be like Dead Rising 2 or Saints Row 2. Valve is a company that doesn't seem likely to just make a multiplatform from an existing game to easily. SE and MS probably will get around to FF14 at one point, SE seems to be sucking up to MS now. 13vs seems real likely to go multiplatform at this point. Splinter Cell has basically gone silent now, and it's been a couple months so I wouldn't expect it going multiplatform for a while.
