As you can imagine, he didn't announce anything, but he didn't outright deny the possibility when asked about GameCube games on Virtual Console:
"We cannot give a concrete answer, because we have nothing to announce at the moment. But there's something I can tell you: we are working on some things along those lines."
Koizumi explained that the console was designed in such a way that it would be perfectly possible to connect future accessories/extensions to the Nintendo Switch (something he already mentioned in a previous interview), so such an accessory could definitely become a reality.
As for Shinya Takahashi, he explained that if Nintendo were to release GameCube-shaped Joy-Cons, they would make sure to add analog triggers. He also thinks the whole thing would be rather bulky and hideous, though!
