You have a point there BUT news from Michael Brookes about "XBONE optimizing and benefits that flow into the PC/MAC version" was officially announced by David. The wording made it unclear to me if it would done on E3 or that MB would release info later this week. Well two more days to go before this week is over. For me a week starts on a Sunday.
Well, Michael is online as I post this and far as I know he's not in E3. So most likely they are doing article today.
