Nintendo E-Shop

Hi there fellows!

I was wondering...Is it possible to port a game developed in Construct 2 to sell it at Nintendo 3DS/Nintendo WiiU E-Shop?

Most likely you will need to look at the requirements that Nintendo has for doing this. What technologies, languages, platforms, etc... they support. Construct uses Standard HTML5, so it is more of a does nintendo support HTML5, Box2d, etc... question, than a does Construct support creating Nintendo Games question...

Make a port of a C2 game to 3DS is apparently possible (since it's a port in a different language, it means basically redoing it from scratch).

If you mean directly publish a game made in C2 to those platform, apparently the answer is no (unless 3DS and WiiU starts to support HTML5 gaming).

The WiiU support for HTML5 isn't very good.

Nintendo's weak hardware + terrible HTML5 support = nope.
