Korg says that it has a “direct, performance oriented interface” and a “sequencer with deep features” but didn’t provide more details than that. Most of Korg’s recent instruments dating back to the original Minilogue in 2016 have focused on knob-per-function controls, so I would expect more of the same here. As for the sequencer, well, Korg did recently he impressively sounding SQ-64, and it would only make sense for them to bring some of the features over from that while keeping the ‘logue line’s Motion Sequencing in tact for parameter automation.
Sadly we don’t have much more to share beyond that. The Drumlogue is still very much in development and, while it might come out before the end of the year, Korg hasn’t offer a release window just yet.
