I have the opportunity to pick up either an x-box or a ps2 for $120; however, im just not sure which one to get

Considering the ps2 has been out for 4 yrs and theyre gonna release ps3 summer of next year (or so ive heard) i was thinking x-box, but i dont really want to miss out on Final Fantasy X or XI, but then again, ps2's online play is free if you have a broadband connection while x-box charges $10 a month. Buuut... then i get back to thinking that x-box has halo and halo II then i get stuck between the choices again

Or i could just say the heck with it and wait til either ps3 comes out or x-box2 and then decide which of the two is better
