I actually like Korg grooveboxes, including the Volcas—I mean, they do have their charm—but I maintain that a single E2 or E2S is the equivalent of at least three Volcas, and easily overcomes most of the above-mentioned limitations of the Volcas; all for not much more money, while keeping with a relatively small footprint.
If you need, say, one Volca for a specific, otherwise menial task, I can see that making sense; but to collect them all or expect much from them… Ya, that I don’t get.
To that end, I have no idea why Korg is marketing this as a v2, or why they even bothered.
Cheers!
