The game doesn't have to look technically amazing to be difficult to port to Wii U. It's running in Unreal 4, which Epic never bothered to optimize for Wii U, so the devs will basically have to do that legwork on their own.
I don't get the hate for MN9, 5 years ago Capcom released a new Mega Man game made by the same developers and it looked like this:
Sure MN9 doesn't look like its concept art, and most likely neither will Bloodstained. Neither ever claimed they would. Both have disclaimers saying they probably won't. Most games don't live up to their concept art, but nobody thinks about that because most games don't present concept art before gameplay. You see the gameplay first, then the concept art long after.
Compare in-game graphics of Skyward Sword to its concept art. People would have been pretty disappointed if the art had been shown first (well, it was, but only one piece that didn't show much and the style did change a lot before the game was released).
Also Samus Aran, calling MN9 a "big budget" game is absurd. It's got a big budget compared to other crowdfunded games, but that's hardly anything to write home about. This game's measley <$5m budget doesn't come close to "big." These are A games at most. It's a bit ridiculous to compare either of them to the likes of DKC Tropical Freeze and Yoshi's Woolly World, each of which probably had budgets measured in tens of millions of dollars.
All that being said, I'm with you in that I don't intend to pledge support to a bunch of empty promises. Playtonic was able to get a basic demo up and running in a fairly short time, Iga could have waited until he had something to show. As it stands, the game is clearly going to get over $5 million anyway, so it's not like they need any of my money.
