From a gamer's point of view I could be tempted to look at 3D sets. However, it's a massive cost outlay after your console, games and then a TV and at the moment only Sony seem to be pushing it. Microsoft haven't mention it once.
Add to that that films can be hit and miss with 3D (e.g. Avatar - really good, Clash of the Titan - Very poor) and that TV content still isn't HD let alone any plans for 3D, I'm going to wait some time before delving into 3D. My next TV with be a HD set and the change on films and speakers.
