"Whirlwind pace" probably just means Fanfests, Media Tours, trailers and things like collabs (Monster Hunter being an example), and rerunning all the events such as FFXV crossover, FFXI crossover, FFXVI crossover, a few moogle tome events, Yokai-Watch, Fall Guys, and every relevant seasonal event in between. There will be so much of that stuff going on that it will feel like a whirlwind pace of events [that any veteran player has already done and isn't interested in].

Not even being negative; I just think the intention of what he's saying probably gets lost in translation and makes it seem like he's referring to the content schedule.

That said, maybe I'm wrong and they'll announce additional patches such as .6 and .7 to reduce the patch lull.
