No, I think the 3DS has like 3 more years before the next Nintendo handheld.

They're focusing on the Wii U, but they're not doing nothing for the 3DS.

The 3DS already has a very huge library of great games. I think most 3DS gamers have a HUGE backlog of great games. The only missing game on 3DS is a Metroid.

No!!! Shigeru Miyamoto already announced that two Metroid games are in development and he hinted at a brand new The Legend of Zelda for the Nintendo 3DS a few days ago too ;)

E3 was focused on Wii U to generate more interest in it, and Nintendo would have recently put more resources into creating Wii U games in the past year.

In saying that the 3DS will not be neglected much longer.

It doesn't play anything like AW. Like at all.  You don't know what "team" is doing it, you just know it's intelligents systems. (They are huge by the way). Do you have a quote that specifically says that they are doing it over advanced wars? 

Oh you don't? Your just...pulling it out your ass?

Right.

I'm quite the opposite, I was sick of them favoring the 3DS over the Wii U, so E3 giving the spotlight to Wii U and pushing 3DS aside made me very happy.

Considering this is a Nintendo console I would imagine that they're shifting their focus to new systems. The last years of a Nintendo console is always slower, although this is the 3DS' 3rd year so it should at least have 3 more years in it.
