Wii U owners, how much internal storage do you have left?

I'm not sure, but I know I still have 1.7 TB left on the hard drive so it is a non issue.

For the price of one year of Xbox Live or PS+ you can get an external hard drive(they even have some options that would equal a 3 month subscription) so the price of expansion shouldn't be used as a negative argument.
