I really hope that the PS4 will keep the traditional Playstation Controller as a standard... I just don't need "new conrol schemes" and having a Tablet PC-Controller as a standard controller would probably only ruin the whole generation...
For me the Tablet Controller is more like a reason NOT to buy the Wii U... Just like the Wiimote ruined so many games on the Wii. If you are used to a normal controller those motion controls only feel like a dumbed down experience since you have fewer buttons etc.
