I didn't expect a Nightmare Geese trailer at all. Now that SNK has zombiefied him, he's even more nightmarish than ever before. Great DLC costume. The new music track is a very good take on the iconic Geese theme IMO, I like it.
@shinefist: I'm afraid there are no hints at an online beta right now and there wouldn't be enough time to host one -the SFV beta program started months before release-, but I'd be very happy if us players got an opportunity to test the netcode.
About the demo, since SNK deleted the tweet about the demo shortly after posting it, it may either be that SNK was simply writing the digital preorder tweet and made a mistake, or (it's a theory of mine and I know it's crazy, but I still wouldn't rule it out) they purposely published that tweet too early to raise some interest in the demo, and will post it again when the demo is actually available. My bet is that we'll get a GGXrd Rev style demo, so lots of characters but no online mode, and it'll be only for those who preorder(ed) a digital copy.
