I must admit, and I know these assets will all have been tarted up with the marketing stick, but those are not 2d games as I was thinking of them. They all look like 2.5D games running on something more powerful than a PS2 for example.
The only question for me really is whether they've successfully captured the old 2D controls of that type of game. I'm not sure if the controller is a circular d-pad or a spinner, and whether it's also touchscreen controlled. For now I'm actually pleasantly surprised at this, and will be receptive to any more information you guys post here.
Also, they seem to have been bitten by the wrong aspect ratio screen thing too, except they seem to have ended up with a landscape screen when they wanted a portrait one, not the other way round like EvilDragon did with the Pyra, judging by the standby screen they show in that video.
