MS won't quit a biz that finally managed to turn profitable with great effort, but while when it entered it it was incorrectly identifying Sony as one of the biggest threats (but they must thank Sony's shortsighted choice of putting too little RAM in PS3 and its high launch price if it didn't become a viable competing general purpose computer), now instead it's CORRECTLY identifying Google with Android and online services as the biggest competitor in the markets where it wants to expand, so it's natural that it puts more resources to fight it and less to fight Sony than in the recent past. But as gaming is an important part of PC and Mobile markets too, and XB360 and XBL are profitable, surely MS won't ever quit it, it will just concentrate less on XB exclusives and more on multiplats (obviously excluding competing console and mobile platforms, except maybe Apple ones, that MS correctly doesn't see as a threat, as as huge as it may become, Apple always sticks to its closed environment, that has some overlapping with competitors in the high end, but never deliberately clashes with them).
