When that $200 price point kicks in, imo 100m is possible, but the only way i think PS3 can reach those sales is if the 360 or Wii become increasingly marginalised in the next few years. maybe its possible to get to 100m because the PS3 line up seems to always be getting better. and MS have also annouced a 10 year plan, if they release a new console before that time, it could impede the PS3's sales.
