I'd say I'm disappointed, but frankly I already knew this was going to be the case a year or so ago and I aired my grievances then; I'm not sure it's all out of my system, but at the same time there's not really much point in complaining all over again. I've just accepted that this is FFVII: The Action Game now more than a more straight FFVII remake, and fine, whatever, maybe it'll still be good. Not really at all what I'd be after for a game with the name of "FFVII Remake", but it could still make somebody happy. Maybe that somebody will turn out to be me. I mean, I greatly enjoyed FFXIV:ARR's combat, and that's real-time (though more cooldown-based than I'm expecting FFVII to be), so who can say?
I see the whole "turn-based combat is inherently outdated in TYOL [year]!" crowd is out in full force, though, and that's as disappointing as ever. It's fine if you prefer action-based combat systems, but c'mon, it's still a valid game design. This whole thing strikes me as similar to that time major publishers all decided at the same time that the horror genre was inherently outdated, deciding to just turn their horror franchises into straight-up action games, until some indie horror games proved them all wrong by selling like hotcakes, and suddenly you have situations like Resident Evil going back from RE6's divisive focus on action to a clearer focus on horror with RE7, to critical acclaim. If there were any gameplay aspect I could say felt outdated about the original myself, random battles might be it. Even then, that's only because I've played various other RPGs that had other systems of starting battles and preferred them, like Chrono Trigger or Earthbound - both of which are still turn-based, note - and that's more about my own personal tastes than being objectively outdated or anything.
Worse still, though, are the people crowing at others who are disappointed the game isn't turn-based. For as annoying as you might find people complaining that it's not turn-based to be, going full-on insufferable yourself is probably not the appropriate response, maybe? Like, I'm happy you've got yet another action RPG to sink your teeth into, but pooh-poohing others who'd hoped for something else (regardless of how silly those hopes were when the action focus has been clear for this long) just seems super shitty to me.
