It's becoming increasingly clear that this direct will fall victim to leaks/inevitable announcements once the delay happened. Apparently Bandai Namco just announced three japanese switch games today, which would've clearly been announced at the jp direct if it wasn't postponed.
With companies like Square, Capcom, and Bandai still going ahead with their reveals, the Laura Kate Dale rumor (which says the direct was postponed because of a specific game in the direct) looks to be true. I think it's a game with some element of apocalypse or natural disaster, which wouldn't sit too well with Japanese people if revealed today (heck, it probably wouldn't sit too well even a week later)
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
