One single sku
Makes more sense than making two.
No one wanted the Xbox 360 Core System because it was a.ss.
No one wanted the 20GB Playstation 3 because it was a.ss.
No one wanted the 8GB Wii U because it is a.ss.
All those consoles were/are half a.ss versions. Majority of the people that ended up with these consoles either didn't know the difference or got it because the better one was harder to get. I'm sure there were a few that just didn't give a sh*t or wanted to save $100.
Also, one SKU doesn't mean less consoles made. Just more of the good one and no sh*tty ones.
