It is looking good, but I'll be waiting for the Steam release in a few years. I suspect it could easily end up being a grindfest like Odyssey and Valhalla before it. As much as I love the earlier AC games, I've not come close to finishing either of those two games.
Bit stuck in this as the moment, as there's a bug with dual-wielding
Once you get far enough in to enable double-assassination and wielding the tanto alongside the katana for the double kill, you'll find you can't switch back to the katana, nor can you use any thrown items (daggers, shuriken, bombs, bells). So you're stuck.
Sometimes a restart will fix it, until the next time you dual-wield, other times it won't.
The only solution I've found so far is to remove the tanto from your 2nd equipped slot and play single-handed only...but then you can't double-assassinate anymore.
