Should I get a PS3 or Wii U?

Dont waste your money on the 12gb PS3, buy one with a hard drive or you will fill that 12 gb in days/weeks.

That's true. I just looked up that it'll only hold a few games. Can one add an external HDD drive? I would be willing to buy an extra one if I end up going the PS3 route.
