18m is probably too low, considering no offline units were counted. Thus, I'm thinking it's closer to 19 million sold by Jan 3rd, which means we'd could be overtracking it by a good 4-500K after next week's numbers arive.

So you think theres about 800,000 Xbox ones, that people have bought but havnt ever hooked up to the internet?

WiiU had 80% online connectivity in 2013. It's probably quite a bit higher now (and thus likely for PS4 and X1 as well), but there are still quite a lot that won't have it connected to the internet. Now remember that WiiU has free online gaming and PS4 and X1 haven't.

So if you don't use streaming services on your console and don't have a PS Plus or Xbox Live subscription for online gaming, there aren't a lot of reasons to connect them to the internet.
