There ya go, 20. The ones bolded I’d say it’s too soon to announce this year. Fable, The Initiative and Obsidians new AAA unveiling is enough for now, best to temper expectations because after all they need material for next year. 

I'm actually glad we aren't getting a 12 min AC gameplay demo with someone running around for 10 minutes then killing a couple of things, A 2 min actual gameplay trailer will be much better.

For me, it really just depends on what else they got to show. Valhalla is a game I'm definitely interested in, so seeing more of it in action would have been cool. Seeing more different things instead could be just as cool, better....or it could worse...idk. All depends what's on offer.

Oh I know there’s more then 20. I just think there’s some they don’t want us to know about yet. 20 games officially confirmed in development for mass gamers to know about is more then feasible. 

My problem with the gameplay demo's are you generally spend 10 minutes seeing very little usually because the person playing it sucks, I think for shows a good gameplay trailer is what they should go with and upload a video afterwards of the walk around 10 minute demo for people to see or done in aftershows for in-depth looks.

The Xbox 20/20 thing is just a play on 20/20 vision with them saying our path to next gen is clear.

I am excited, but not overhyped. I think we'll see a bunch of multiplatform games, some of which will turn out to be really fantastic.

Its just an opportunity to get a better look at the graphical prowess of the system.

60fps will be the standard output, but the architecture allows us to support up to 120fps.

About what I expected, A few interesting games thrown in there and an Xbox exclusive The Ascent.
Yakuza Like a Dragon been a Series X launch title is pretty cool.
