Alright, let's rationally discuss this:

Would an Animal Crossing for Wii U really be a "megaton" announcement?

I mean, come on.

I am one of the biggest Nintendo's fanboys i know, and even I couldn't care less about Animal Crossing.

Megaton what be something unexpected, not something we know will happen, like the next Metroid for example.

Nintendo: Mario RPG co-developed with Square together.
Sony: Horizon would have been one if it wasn't leaked. I'd say the next monster hunter or Dragon Quest exclusive to their systems would be a megaton.
Microsoft: Next GTA times exclusive. Or if we go by exclusive games, Microsoft striking a deal with a third party( like with Sunset Overdrive), but bigger in scale this time, like say the next Left 4 Dead being exclusive to it.

The Last Guardian is not happening... ever I don't know why people consistently say it will be announced at EVERY sony event.

Some realistic Sony megatons: Uncharted bundle, new Crash game, Last of Us 2, Kingdom Hearts 3 or Final Fantasy 15 announced as a timed exclusive.

Microsoft: Some more 3rd party exclusives (Timed & console exclusives).

Nintendo: I cant really think of any Nintendo megatons maybe a Metriod game but that's unlikely.

You gotta admit, the meltdowns would be incredibly entertaining to watch. I can seriosuly see it happening considering Capcom's condition and MS' willingness to spend tons of cash.

The next L4D being exclusive to the X1? Not even in MS' dreams!  At least 80% of the gamers who play L4D2 are playing it on Steam! :/

FF16 announced (for PS4?) and will release a year after 15.

You really think the other SE departments are sitting doing nothing? If SE were sensible they'd be working on 16 and 17 right now.

.... wait, I forgot, SE aren't sensible.

Yeah true, but that's why it would be a MEGA TON
