The largest issue is exactly what you stated. I'm a PS3 owner who bought the Wii U day 1 because of games like Zombiu, Ghost Recon (shelved) and the fact that I can play off-screen. And what annoys me is when 3rd parties complain that their multi-plat games aren't selling well. Well of course not, half your games are already on other consoles for lower prices and have more features.

I already had AC3 and Black Ops 2, because AC3 came out earlier, and Black Ops had a larger online service on PS3. Sniper V2 and Deus Ex: DC priced at $50? for the same price I could get V2 on PC with dlc and the nazi zombie missions. For $30, I could get directers cut on PS3 with the same content, just no touch interface. 

Except when a major game on a Nintendo console doesn't have spectacular first week sales, it's declared a flop, people call out Nintendo fans for not buying enough of it, and the console is declared doomed. Doesn't matter what the game is, whether it also flopped on onther consoles and whether Nintendo fans had/have very legitimate reasons for not buying it immediately, or ever.

Take a game like Rayman Origins, where the Nintendo console leads the rest in sales, people still call out the Wii U version for not jumping way ahead of the others. The game released at the same time on every console and flopped on all of them, yet the Wii U gets special mention.

I'm not even going to go into Mass Effect 3, Madden '13 and Fifa. I've done that to death.

.. as I was saying people will remind us of this.. that "Nintendo fucked something up" .. so it is all their fault.. no matter what it is.

It´s just about business. The install base is small, they don´t believe they can make money selling their big-budget titles on WiiU, then they just produce "crap versions" of them for it. It´s the same problem with Vita. Didn´t you ever wonder why Capcom don´t even consider launching Monster Hunter 4 for Vita, or why Rayman Legends is considerably shorter ? The same goes for WiiU, 3rd-parties don´t want to spend a little extra money working on WiiU versions

And this is a shame, because there are a few games that actually sold better on WiiU than on other platforms, like Rayman Legends, Sonic All-Stars racing Transformed, probably Just Dance 4 too (after holidays). So there´s an audience on its console, but 3rd-parties are just ignoring this audience.

Now it´s easy to blame Nintendo for everything, but gamers never, unfortunately, NEVER understand that most decisions are taken from a business perspective and always justify their opinions based on bias.

i think you summed up the big three pretty well. 

so the same happens to playstation systems as well.
ps got bioshock late, monster hunter frontier, minecraft, COD and skyrim DLC's, mass effect 1 and 2, chinatown wars, red alert 3, alone in the dark, sine mora, section 8, plants vs zombies.

looking up a few more online (dont quote me on these), it also got Ninja Gaiden 2, Limbo, Braid, oblivion, Lost Planet, Overlord, Castle Crashers, Tales of Vesperia, Star Ocean IV, Eternal Sonata, Deadly Premonition, Enchanted Arms.

not all of them are as late as deus ex on wii u but people still wait for them and do buy them even if there isnt good advertising surrounding the late launches. On nintendo, if you launch a game and dont have decent advertising then good luck.

Theres nothing to guarantee that sacrificing development time on ps360 for wii U to launch them at the same time will make more money for them, and as a nintendo fan once told me 'its not the 3rd party developers responsibility to sell consoles' so its not their fault.

It's not their responsibility to sell consoles, but it is their responsibility to sell their own games. So yes, it's their fault. They're making games, not bothering to attempt to sell them, and then bitching when they don't sell that well.

... they're not losing money, that's the point.  As far as consumer confidence, most gamers don't even keep up with who publishes what.  The only people outraged are the forum-goers who get outraged about everything.  The average person isn't writing Square and other publishers into an anti-Nintendo Death Note.

As far as me hating Nintendo, stop it.  The only thing I dislike is that persecution complex some Nintendo fans seem to revel in, even when the same thing has happened on other platforms numerous times.

"but it is their responsibility to sell their own games"

thats what I said about capcom/MH, but nintendo fans dont agree with that statement.

you cant have it both ways, its got to be one or another.

no it didnt, and the never begged for a port it was always multiplat
