That's debatable, but how can one debate when they don't play the competitors games.  I say this towards "most" Nintendo fans who don't play anything other than Nintendo games.  Mario Kart 7 is a good game to a Nintendo fan, but has that same fan played comparable racing titles.  They could think Wipeout 2048 is the best racing game ever but because it's not Nintendo they haven't played it and have no interest.

PS3 is the only one that's ended up selling well.  Most people will say it's too early to tell for the Vita, but I'm of the opinion that it'll get games here and there, but otherwise, the system is dead.

Here's something that might interest you.

Yes it is debatable, I love me some  Nintendo Games but i kno other games as well, i'll respect which is better. I liked FF/KH and think those games (Not FF 11-13 since i didnt play those) are better than some RPGs that nintendo has but Games like Chrono Trigger/SM Legend of Seven Stars/Paper Mario+TTYD are better! X looks more impressive than any ps4/X1 i seen but thats my opinon obviously (i not talking graphcs so pls dont mention it). I love Halo, GoW is bad ass but maybe Bayo2 might be better than GoW4! Nobody can judge yet of course. Name 1 PS4/X1 game tht be more fun to play with your family/friends with you (locally) than MK8/SSB4/SM3DW? Exactly

Anddd? Yes we know WiiU sucks in sales now. So did PS3/Vita/GCN. Its been almost a year, never sell anything short or you might mistake it like people did with the 3DS (Which has Great Sales for a Dead Handheld Market Generation )

Lol nice argument, your point of why pc gaming is cheaper is the fact that you need to have parts in advence, that are ofcourse not included in the total price, and you need to steal the OS untill the glorious steam OS is released lawl

Currently no family game I can think of that can be locally played with anyone that's worth getting for the PS4, but there's always the potential for a future LBP. 

What about Kinect Sports Rivals on the Xbox One?   Since the majority of most families don't play video games, I'm sure they'd enjoy yet another Wii Sports knock off more than any of the Nintendo games you listed.

As for your RPG list.  I'm a huge RPG fan, so I could point you in the direction of many games better than the ones you listed, including Chrono Trigger(not saying it's not one of the best ever made though.)  I'm interested in X, but haven't played it so not going to say whether or not it's better than what I have played, but will say "probably not."  The RPGs you named  seems mostly limited to Nintendo consoles though.

We also know for sure PS4/X1 won't have  Mario 3D World, DK Country TF, Mario Kart 8, Smash Bros., X, Bayonetta 2, Zelda, and so on.

PS3 never even got close to selling as bad as the wii U on a weekly basis, for the vita and gamecube they are not really helping the point you are trying to make unless if you think the wii U selling around 20mill is a great success

His point was there's a lot of 3rd party games not coming to Wii U, no idea why you posted Nintendo 1st party games.

The counter point is that those games arent here yet. So why not just buy your secondary console first and wait for the games you're listing that you want to play when they get released. You'll probably find better deals on the console then than at launch without any of the growing pains that stem from a launch.

The WiiU on the other hand is a year old now and you can get some sweet bundles with it and Black Friday deals off it. Unless you GOTTA have that Killzone immediatly.
