Do you think Nintendo regrets the announcement of Super Smash Bros. 4 for 3DS ?

In a way, yes.
I think it`s safe to say Iwata expected more of both consoles, especially of Wii U.

Still, as things are today, 3DS can live without it, but Wii U can`t. And having to share sales with 3DS is going to harm Wii U.
