Now, if you read carefully my message about resolution, one week ago, in fact, i explained in advance the situation that could arise for third-parties ports, for a lot of reasons (ports, impressions before the latest dev kits were available to them, use of the padlet, lot of room for improvements here and there, etc. etc.).
I think i even said that if someone (not a techie/artist, so a director like the Vigil one can holds this role) compare directly, TV to TV, a Xbox360 game, and the Wii U port, he could say in this specific context that i so much stressed on, that both versions are roughly "on par", with in reality an edge for the Wii U one, but not like a "PC on full Ultra options, 1080p". It doesn't exclude the possibility that Darksiders 2 Wii U have smoother framerate, better textures, etc. A lot of people can't really discern at first sight the difference between medium and high textures in some PC games for example (or viewing distance, etc.), but with time, they'll see it. The last part is just speculation, an explanation of how someone from Vigil can say "on par". And this is heavily related to the studio choices also (maybe they want to use their limited resources primarily on the Wii U new control schemes, and will see for the graphics later, or even decide to not touch this to an extent that you'll say "it's clearly a more advanced version visually"). It could be the engine/way to control the image quality in their project, a lot of multi-ports (PC/PS360) are far from frostbite 2 stretching, even with the options set on High on your beast computer, what is displayed doesn't distinguish itself so much from its console counterpart, you have to change yourself some files, apply via graphic card drivers or other method tons of AA/textures filtering, etc, to really spot a great difference, and i think Darksiders 1 is like that. It could be related to marketing/PR stuff, the game isn't released yet and they are presenting/promoting it in a lot of medias right now, if they say "the Wii U version will be more beautiful", they could shoot themselves in the foot for their current gen sales, a non-negligible part of gamers who want to buy this title could decide to wait for the Wii U one.
Clearly, i don't understand why some people are panicking because of this since yesterday.
