Absolutely, but why would Microsoft hold back their announcements of their first party updates? They made a big deal at the end of the show about which of their own games will be updated, and it was a small list. I have some serious doubts they're going to add older games like MCC, Halo 5, Ryse, Tomb Raider, Sunset Overdrive, Ori, etc. etc.
You realize that the X is 5 months out, right?
Sony did a pretty good job with this even updating Knack and Infamous. Although those improvements weren't announced/released till after the Pro came out, so maybe there is hope.
