HAL Laboratory has confirmed work on multiple upcoming projects, none of which are related to Kirby. (although it may be that a Kirby title is in development as well)
Awesome! BOXBOY looks like a great game, which I still need to download. It'd be cool to see some more unique titles like that. HAL is honestly one of my favorite developers, they're always really creative.
Certainly, as you say, the Kirby series is HAL Laboratory’s main development focus, but we actually have several other projects proceeding along in parallel (not that I can give details on them right now, of course). We also have a few experimental projects in the works with smaller teams, so there certainly isn’t any rule that we must be involved with Kirby projects. Like I discussed in the first question, BoxBoy got its start as an experimental project along those lines.
