AAA? That's unexpected. I never thought we'd see another one on those on Wii U.

What could it be? Tomb Raider or GTA is highly unlikely. Maybe Mass Effect Trilogy. I have no idea what else it could be. Or wait.... Alien Colonial Marines

That's what gets me, there are no obvious candidates I can think of.

Mass Effect Trilogy is old, old news. A COD port would be handled by Treyarch's Wii U team. Assassin's Creed Rogue is a long shot as Unbisoft has washed its hands of Wii U. GTA/Tomb Raider are, as you say, a remote probability. 

It's a head scratcher.

Skyrim?

A game from 4 years ago? That's a bit of a long shot, isn't it?

Maybe they want to make a remaster of Skyrim, and they are bringing it to the WiiU too.

What other game could it be?, MGRising, Red Dead Redemption, Resident Evil HD, the next CoD, Destiny, Kingdom Hearts 3...

Resident Evil, hmm. Resi sold OK on Wii, so it might be not impossible. But Capcom probably doesn't order the port at Tantalus/Straight Right. Look at the games they did in the past, it all looks like western entries.

Destiny is another thing. Not impossible that Activision could order this. But Destiny is centered around online play, not the thing gamers on WiiU concentrate on. So maybe?

COD? Was done by Treyarch in the past, why changing that?

I wonder if their "AAA" game port is or could it be some "AAA" movie centered tie-in game ...

A possibility. Which major movie tie-ins are released on PS4/X1?

I'm stumped.
