Didn't catch on? The Wii was Nintendo's best selling console ever (apart from the original Gameboy), and outsold the PS3 from the same generation (and ever Xbox ever). It's quite likely that the Wii is the reason why PS3 was Sony's lowest selling console.

Yes, didn't catch on. Wii had terrible attachment rates, meaning people bought a Wii and Wii Sports or something and then nothing else.

Yeah it didn't catch on. The Wii U bombed, Kinect on xbox bombed and the actual number of games that took advantage of the features in either was pretty low compared to the total games released in those generations.

Wii/kinect is a gimmick that a finite number of good games could take advantage of and once they'd been released there wasn't really anywhere else to go.
