A significant price drop and a lot of 'best place to play' would do well for XB1X. MS can effectively gloss over XB1 and present everything in an XB1X flavour for Maximum Impact and the best presentation of these new games. I can see third parties happy to have themselves highlighted at E3 in such a message. Also by having XBox cross-platform, well, being a platform rather than a device, games can be showcased on ultra ultimate supremo PC settings and still be valid. E3 is all about visual impact and getting social shares, drop dead gorgeous visuals are best for that, and eye-watering PCs are the way to achieve that. Either way, any game being presented on XB conference can look better than the same being presented on Sony conference, so makes sense.
