The Wii doesn't really sell games either. The attach rate for the console is poor in comparison to its competition. Even though the Wii sold 30% more units worldwide than the Xbox 360, they only sold 13% more games worldwide. In North America, the biggest market for console games, the total number of Wii games sold is roughly equal to the total number of Xbox 360 games sold.

He's talking about the possibility that one or both may prevent used games sales by tying games to the console account they're first used on.

The Wii U is, so far, a huge failure, probably for many different reasons (the name is a big one), but one of the main reasons is likely the poor specs, it's just slightly faster than the old Xbox 360 and Playstation 3.

If it were a "real" next-gen console with specs similar to those of the upcoming Xbox and Playstation, instead of just essentially being a last-gen console with a fancy controller, a ton of people would care.

The Wii has a low game attach rate compared to XBox360/PS3. People buy the Wii for its gimmick and maybe some Mario, but stop there.
