I'm sure we'll see some stages, but it seems they are just going to trickle information till TGS. They did similar with DoA5 though that announcement was much earlier so E3 got a huge content showing and even more at TGS.
I hope they flat out show stuff and stop being cute with these silhouette teasers, teasers are so LR xD We can get more hype and such just by flat out showing everyone since we didn't really need a detective to know it was Leifang and Hitomi xD
