"So... is it happening?"
I'm pretty sure you'll get no answer anytime soon.
TW will probably be all hush hush about it until it's actually near completion, unlike with RO2.... lessons learned after all.
When its ready, they'll just go "Here it is, buy it and enjoy it" rather than having to deal with "But you said this would be in it, or we saw screenshots of that, you said it'd be released at this time.... you PROMISED!!!"
Could have also been edited in Photoshop to list off a bunch of random games being tossed around in rumors just to stir the pot and get people talking.... I could do that.
In fact, maybe I should, just to screw with people..... toss in RO3, Half-Life 3, Team Fortress Classic 2, Chivalry 2 Alpha, etc.
