I respectfully disagree with you friend.
R.O.B. may reperesent that, but honestly with the ice climbers coming back, it hasn't been confirmed but they were mentioned in an interview as making problems in the 3ds version and also in the customized move trailer kirby was shown using a move that was oddly similar to the ice climbers freeze breath move, and also their is the polar bear who shows up constantly, doesn't really mean much but added to the other facts it just increases the percentage of their chances to 90 unless they somehow didn't fix that 3DS problem, already represent the NES. On top of that if you have Takamaru in the game, who i am not reaally sure about but he has that Nintendo land game so I think he may be making some sort of comeback, smash would be a good opportunity to do this like how they did for Pit, they really don't need his representation taking a third spot. Sure the NES was obviously important, but 2 for this game is still a lot, they, more importantly, need to advertise their new games since the Wii U is having its sales problems to promote future games success. Also I said in my last post that Game & Watch represents that whole period so I think that what I say somehow means the opposite of this makes no sense. I just think that the Ice Climbers and Possibly Takamaru would be enough, they still need to advertise their new games.
Wha? Ice Climbers are a completely different situation to R,O.B.
Sakurai wanted to revive an old character as a callback to that era with Ice Clibers and he did it again with Pit in Brawl.
R.O.B. on the other hand was added in the same vein as Mr Game & Watch (Who returned from Melee) to represent the entire NES as a whole, which is why his signature stage in Brawl was Mario Bros, an old game that was on NES that still had its 8-bit appearence, you know, just like the Balloon Fight stage we've seen on the 3DS version.
This is what happening, in Melee, we got a retro rep and a console rep
In Brawl, we got a retro rep and a console rep
In this game, we will most likely get another retro rep and another console rep.
And what your say ing doesn't even make sense for the way you view things.
According to your logic, Brawl had Pit, Ice Climbers and R.O.B.
But Ice Climbers, Takamaru and R.O.B. is too much?
Ice Climbers are retro reps who started the traditionof adding a retro character in each game
R.O.B. is a conole rep who follow the tradition of a console rep that Mr Game & Watch started.
So basically
Retro:
Melee: Ice Climbers
Brawl: Pit
4: Probably Takamaru
Console:
Melee: Mr Game & Watch
Brawl: R.O.B.
4: Probably Mii
Cutting R.O.B. doesn't make any sense no matter which way you put it.
He is an important part of Nintendos History
We wouldn't have any more NES characters by your definition then we did in Brawl
He is the exact same Shoes Mr Game & Watch was in back in Melee
He has a unique Moveset
Sakurai has already mentioned that he wants to bring back as many characters as possible
Nintendo clearly has a soft spot him as shown by his many appearence thoughout history (See MKDS, Tomodachi Life, F-Zero, WarioWare, Star Fox and more)
He literally has no reason to get cut at all!
