Nope. Haven't bought a console since the PS2. except the Wii as it had a point to me buying it.
As I have a PC, buying a Microsoft console would definitely be a pointless waste of money - if what I've heard about Windows 8 is true [May be the one reason I'd install it on my old, crappy laptop], and Sony would have to put out some absolutely legendary games to justify me touching their console.
I really see no point in buying a console next gen though. It will be more expensive than upgrading my computer, it has inferior possibilities and specs, and would get used very rarely as my family generally use the TV for watching television, and a console would just sit there gathering dust.
