I'm leaning about 75% toward a PS4 due to the Japan-centric titles (Gundam, SRW, mecha, Final Fantasy, JRPGs, etc.) that will probably be there. If they announce region-free capabilities, I'm 100% in. I just don't see Microsoft going after the Japanese developers that cater to my tastes like they did with the 360. Definitely not buying on day one, though. Probably won't pick one up until sometime in 2014.
And handhelds still do nothing for me anymore.
