Have you forgotten the Geoff Keighley/Epic thread?
Here's the important evidence.
I dug up some reaction posts for you.
This excludes a plethora of "Wii U is current generation/not next generation" and "This isn't surprising" posts.
Tell me. Where in any of these posts does it say that Wii U will be able to run some form of Unreal Engine 4? There are posts in that thread that say things like, "Maybe Unreal Engine 4 can be scaled." These posts do not do that.
Do you speak for all of these posters when you say they
meant to say Wii U would be able to run a scaled-down version?
I'm not trying to draw attention to these specific posters; I'm just asserting the fact that, after that thread, many people did not think Wii U would be able to run Unreal Engine 4.
My apologies for derailing the thread, but I felt like I had to say it.
