When did the 3DS come out again?

Early 2012, but really it was supposed to launch for holiday 2011. 

It was worldwide March 2011. http://en.wikipedia.org/wiki/Nintendo_3DS

And since it takes 3-4 years to make a new console, I would say yes, Nintendo is working on a new console. Although their new system may not go full steam until the new HQ is built.
