The real reason why they probably won't copy Nintendo is that the Wuu Pad isn't nearly as compelling as the Wiimote on release. Besides this both Microsoft and Sony have their own options to support similar functionality that they can pursue if they want to, Smart-Glass and Vita compatibility. If the pad really is a 'game-changer' they can easily push their own solution quickly so this isn't a repeat of the Wii where the response from the competitors took four years to come to market.

i think sony and ms wil come out with some kind of tablet controller. they both copyed the wiis motion contoler

I think it's likely the PS4 and/or 360 controller might have a touch pad - like Ouya's or Vita's or possibly a small touch screen in the middle. Something non-intrusive but big enough to get maps off the TV or communicate other info or just be used to suppliment gameplay and for tablet games being ported to XBL/PSN. Could just take over the space where the Xbox logo and start buttons are, maybe extending outward and upwards a little. Those lost buttons would become virtual on the touch screen.

I don't think it'll be a major feature like it is in WiiU. In fact merely have a small touch screen would screw Nintendo because all 3rd parties would build for Nextbox/PS4 and port to WiiU. So if 720 has a tiny touch screen, whatever they use that for, so will the WiiU port, despite being so much bigger, making WiiU pretty irrelevant to core gamers.

Kinect isn't exactly a copy. It's a far more advanced tech, I dont' see it as a good comparison. And the tablet controller isn't as appealing as the original Wii motion controls. That was completely new and unique. A tablet is something that we are used to see since the first iPad.
