Which of these milestones would the Xbox360 reach before the end of year?

[markers]

im gonna predict low, i dont think it will be much of a boost (of all said mentions of games/deals n such.) so without further ado i say....24.6 mln so they gain 4.6 mln

a harder question would be can ps3 hit 20 mln by the end of this year? doubtful but holiday season looking good for them
