I've played both Rayman games, one the ps3 and the other on the ps4. Both games were amazing :)
I'll try the Pikimin demo and see what it's like.
As for not wanting a gamepad, I can see why some people may not find any use for it but it is an awesome piece of kit. You can't really appreciate it until you own it. I've found it better than both, the Kinect and it's features, and the ps4 eye and it's features.
Not linked a vita to the ps4 yet so I can't really say how similar it is. The gamepad has more use than what people give it credit for
