If you read the article its what he wants and predicts, not what is going to be there.  More so he says "game syncing/roaming through xbox live" with phones and computers so you can play your game on Xbox and then go to your computer and play it on there as well.  Here is the piece about XBO

Xbox and PC gaming

Microsoft has a rather mixed history of PC gaming. Initiatives like Games for Windows Live failed miserably, and the company has never managed to transform its success with Xbox Live on the console over to traditional PC gaming. With Phil Spencer now in charge of Xbox and gaming at Microsoft, things are starting to look a lot better. Spencer killed off the Kinect bundle, cut the price of the Xbox One, and even helped acquire Minecraft. His efforts on the console side have not gone unnoticed, but it’s time PC gaming got some much-needed love from Microsoft.

That should be the main focus of Spencer’s participation on Wednesday. While Microsoft can’t match the power of Valve’s Steam service, realizing the potential of cross-platform play and bringing Xbox Live to the PC in a way that makes sense could help, alongside an improved Store to access popular titles and indie games. Microsoft has long promised games that let you play on a phone, and then resume on a console or PC. Pitting Xbox One gamers against PC players in the same game could be an option, but Microsoft now has the infrastructure to enable true roaming games across phone, tablet, PC, and console. We're expecting to see some of that on Wednesday. imagine playing Xbox One games on your Windows PC, or buying a single game that you can play on your PC or Xbox One and the game state syncs alongside achievements and Xbox Live integration. Wednesday could hold lots of possibilities for gamers, but a commitment to PC gaming will be a key part.

I will watch the show, good hour for me. But I'm afraid of doing it lol

I want to see VR there(getting it out of the way, literally), also smart glass being for XBO what vita is for ps4. 

Small digital games having cross buy is a nice idea, like ori, max, kalimba.. I'm in favor of these being on pc, they need to be exposed to the most people possible.

Cross play is fine with some games, not XBO exclusives, I want to see RTS with cross play but we need mouse+keyboard support first for XBO, 

But more than this, is going too far..

If the above is correctly predicted you would be able to sync your xbox live account with PC/XBO/Phones to play your console games on Phones/PC and your phone games on PC/Xbox and your PC games on Xbox/phones through Xbox Live.  Thats great f true.

MSFT is against cross-play but there has been complaints over the years so i can imagine they will allow cross-play with  "some" games.  

Nice new indies/games :).

I'm not sure. Im not expecting any big or surprising announcements but hopefully I'm wrong. 

That looks like quite an interesting game actually. Might have to try it out.

at what time is the event?

5PM UK time what that means for you time you have to look up yourself =p.

A bit light lol say that to my wallet yikes

thx, so I'm able to experience it.
