Does the Wii U playing Watch Dogs say anything about how it would compete against other next gen consoles?

[Sensei]

If PS3 and X360 run it, Wii U can also run it.

Which isn't much of an achievement as we know all these three versions will probably not be PS4/720 levels of graphical quality.

The best news is that Wii U is getting a port and it should be decent enough to be at least above PS3 and 360 versions.
