Also know someone personally who saw the ad too. Ad was pushed a bit early by Twitch, but spills the beans that Capcom seems to be shadow dropping the demo later today during their Capcom Showcase (at 2 PM PST / 5 PM EST / 10 PM GMT), probably after the Showcase itself. The ad also shows all platforms with that claim, so seems the demo will hit all platforms in less than 24 hours from now.
I think many suspected it would, but nice to have confirmation, and also soft-confirmation it is apparently not a platform timed exclusive.
