Worth noting is that the PS3 used boxed footage created using an SDK on a “comparable PC” for their E3 2005 demo. XBOX/360 was probably the same, it *IS* a PC after all.
At least the Wii U used footage from actually comparable hardware. It’s not the best scenario but worse has certainly been done in the past. Let’s not forget that the E3 2005 PS3 was so different from the final one that it’s hard to believe it wasn’t a fake. I mean 2 HDMI and 3 LAN ports? Get real…
