Yea, some aspects of Japanese culture and marketing strategies can be a bit strange at least to me.

At this point I'd really like to see some new fighting games coming from somewhere other than Japan

India, Australia, Germany, France, Ghana, Nigeria, Dubai, Quebec, Montreal,Sweden, Abu Dhabi, Spain, U.S. , etc. Look at how receptive MIdway/Warner Bros is to Mortal Kombat fans

Maybe a fresh approach a new start for fighting games. Japan's fighting games are getting to be a little monotonic. And they don't seem to listen that much to fans outside of Japan. The new indie and upcoming game developers from other countries and cities from around the world seem to be more open and connected to the appeals from their fan base.

Just a fraction of the money that Sega is putting into all of those Yakuza spin-offs that were announced at TGS 2022 could have taken VF5US well beyond where it is now. There were many , many good requests given to Sega from many of the loyal fans on VFDC. Yes, some things they heard, but they left a lot on the table. And by the size of the budget the Yakuza spin-offs are getting Sega and RGG had/has the money to have gone a lot further with VF5US.

I'd like to see other countries get seriously into the FG thing

I think Harada and co. are still reasoning like fighting games are a niche genre, but when each one sell more than 10 million (MK, SF, Tekken, even VF5US but this was free), it's crazy to still act like "we are all at risk of failure, let's spread so we can avoid to fight".

Any VF announcement (VF5US's DLC or a VF6 teaser) would be greatly helped by the momentum generated by SF6 and Tekken 8 announcements.

I think the most curious thing was that RGG(Yakuza) are now using Unreal Engine.
Which means the next Virtua Fighter or spiritual successor will be using it.
Won't see an announcement most likely until next year (30th Anniversary)

RGG switched from their Dragon Engine to Unreal Engine 5 WTF R U Sure

That would mean VF has to be ported from Dragon to UE5 that will take time and resources. Also that will change look and feel of VF. Game Engines are not all created equal.

EA's Frostbite, RGG's Dragon, Unity , UE4, UE5 are all very different animals
That could definitely push things back to 2024, 2025 especially if Sega/RGG is putting most of their money into Yakuza spin-offs
