Topic: Kingdom Hearts 3 now using Unreal Engine 4...

If vgchartz is accurate, the Wii U is still ahead of Xbone in this generation.

Especially since those are pretty much the same numbers they've had since mid-August. Not that I would expect a huge jump in sales, but a few high-profile games did come out (Madden, Destiny, Project Spark), and yet they're still saying more or less the same amount...

Is there a more reliable source to check sales? (I am of course talking about a one stop website that compiles sales data and not having to hunt down individual articles) Also is there a source that makes you think XBox 1 has passed the Wii U in sales?

This. We've already known for a while that Wii U was at around 7 million, with Xbox One coming in around 5 million. The figures are put up around the same time. Usually the only flaw in those charts is that they're a few months, at most, out of date. Otherwise, they're fairly accurate for when the numbers are posted.

The only charts that aren't completely accurate would be software, because of digital sales.

In fact, Wii U is still beating out Xbox One and PS4 in software sales by double, so it's not like Wii U is doing as bad as some people think it is.
