Start getting confused about getting a Wii console, Didn't know that now it has new model called Wii U. After go through a few thread, can i conclude that I need to have the following if I want to play motion/sports game of wii:

1.) Wii U console set (with gamepad)
2.) WII REMOTE PLUS + NUNCHUCK
3.) Sensor bar (in order to play Wii game?)
4.) Games

Never play console game since PS1, can anyone suggested where can I get all this for me to play wii + wii U game?
