I'll hopefully be getting one soon Insha'Allah.
Simulview is the biggest draw for me, considering how plenty of first-party titles are supporting it (KZ3, Motorstorm Apocalypse, UC3). Plus, since it's built specifically for gaming, I'm sure it won't have the same kind of input lag that all existing 3DTVs are plagued with.
Another reason why I'm opting for this instead of a larger screen is because hdmi 1.4 only supports 3D at 720p/60Hz for gaming (1280x1440, to be precise). There's no real advantage of having a larger-than-32-inch screen, because you simply won't be getting the same kind of detail that you would with a crisp 1920x1080 picture.
It would be best to get this now, and get a 3DTV later once hdmi 1.5 with Full HD 3D @ 60Hz is possible.
