Tsk tsk, Nintendo games have some serious attach rates. Wii U having a big attach rate would mean the overall attach rate (total software sold vs total hardware) would be very high.

Im curious about amiibo sales

You don't Say? :D
Yup, pretty impressive...

I'm seeing a trend here.

I'll confess that through the last gen I barely used my wii and wasmvery much a 360/ps4 guy, but this time around I buy a ton of games for the wii u and 3ds as they're just consistently good. I anxiously await most wii u releases at this point, it's definitely my preferred console so far over the ps4 (don't have xb1 yet).

It's because Nintendo knows how to make good games but not good consoles

Wii U is very good console, just with bad sales. Also, games on first place are thing that define every console, not sales or architecture.

For Mario and Pokemon*

Hopefully we see more Splatoon type successes in future.

Mostly attributed to the low hardware sales, but shows how much fans love Nintendo games.
