For all you guys saying EA, the title says least favorite developer, not publisher.  Mine would probably be Square Enix, making us wait so long for KH3, the current batch of terrible Final Fantasy games and they didn't make a sequel to the World Ends With You, even with the great scores.

It doesn't really matter.  Your points didn't really make much sense anyway.  Nintendo doesn't keep releasing the same stuff.  The games that they release that is the same over and over is the stuff that sells really well (because that's what the consumers want from those games).  
Talk about contradiction
It wasn't a contradiction.  If you re-read what I said, the second sentence was an aside for the games that they DO do that too, the first sentence is to say that their games consists more of new stuff than "just the same stuff over and over again."  I should have known you would take it out of context.

However, there are plenty of games where they changed a lot and even have new IPs.  It's ridiculous to assume that Nintendo (actually Game Freak) is being lazy with current pokemon games.  If you were actually working with the team that makes the games, you would know better than to say it's lazy.

Really pokemon is the epitome of rehash, adding a bike and running shoes is enough for a new gen
Not really at all, because each pokemon game released adds new pokemon.  You would think coming up with new pokemon would be easy, but it isn't.  Some pokemon are lazy designs, but most of them actually have a lot of work put into them.  Not only that, but you must not know anything at all if you think pokemon "added a bike" for a new generation.  Pokemon has ALWAYS HAD A BIKE.  Also, if you haven't noticed, there is a shit ton of new stuff in Pokemon X and Pokemon Y (not including the rollerskates, the new pokemon, and the new type).  You also have the 3D graphics, the 8 directional movement, the ability to mount some pokemon, horde battles, sky battle, new skills, enhanced pokemon cries, enhanced EV training, and that's just scratching the surface of the new stuff they added.  There's most likely more than we even know that's new about the game and they have already said so much.

Game Freak (not really Nintendo) has its reasons for not making pokemon into that kind of game.  Pokemon games already sells 10mil no problem.  

having pokemon selling 15mill on handheald and 10mill on console would be good for Nintendo don't you agree
That isn't Nintendo's decision to make, and there is absoltely no guarantee that pokemon would do that well on a console anyway.  It is likely that people would prefer pokemon to stay handheld.  Only reason you may hear many people saying they wish it was on consoles is because they are a vocal minority.  This happens all the time.  You see a lot of people asking for something, and it may end up that those people who you see asking are actually the only ones.

Going back to your first point, here are the games that I say are the same thing over and over again:  2D Mario, Mario Kart, Mario Party, Pokemon to some extent, and the sports games they release.

That list doesn't have games like Metroid, Fire Emblem, Xenoblade, Kirby, Paper Mario, Mario & Luigi, etc. in it.  Just because some games have similar elements in it, does not at all mean they are just the same thing over and over again.  If that were the case, you would have to make this argument about any developer that has released any sequels ever.
