I doubt it. DVD are maxed at 8.5GBs and they can barely fit in games now. That being said, it's life will be a lot shorter than the PS3 or Wii making it unlikely that it will be around long enough to hit 70million. I mean they've yet to build a console that can survive past 5 years and with such small limits on the hardware, mainly game storage I don't see how the 360 will best the original XBox by much. The PS3 is also catching up in consoles sales making it possible for 3rd party devs to sell enough on one console while not being limit by a mere 8.5GB limit. 3rd parties will most likely jump ship; Im thinking about how so many 3rd party devs were attracted to the PS1 and ditch the N64 because its storage held back developers.
