Technically it was not mission accomplished,

by Sony still have having MGS4 as a PS3 exclusive, they reaped the entire hardware boost the series would provide. Also, with future releases, all of the MGS fans are invested in the PS3. As such, the 360 version of MGS:Rising will likely get outsold by the PS3 version by a fair amount and the sales they do get will largely consist of people who wouldn't have bought a PS3 anyway.

on top of this the last sentance of the article sums what you said up pretty well.
