The one console I would always recommand and invest money on over even PS4 and XONE, is a Wii U.
The price is really good, besides it'll take ages for the emulator to be able to emulate currectly, let alone be optimized for playable speeds (that's if you got at least a $1000 pc).
I don't see any reason why Xeno won't work on Loadiine, especially after the latest version that came out yesterday which raised the compaitibility to over 99% (only platoon has issues as far as I know for now).
So yeh, buy a Wii U, I would recommand buying an unoped one so you're sure about the firmware version it has, due to auto-update, almost any user who used wifi on his Wii U is already on the latest firmware now.
