1. Resident Evil 9 did receive a delay from a reveal last year, if they delayed it its because they think it needed a bit more time, so they're not rushing it.
2. RE9 is a really ambitous game, it's taking longer simply because it's a huge game.
3. Onimusha is a long dormant IP, so is Okami 2, so starting marketing for them now makes more sense as more people to sell on them. Resident Evil meanwhile is very popular, and RE9 will likely turn out amazing, so less marketing time is needed.
So keep in mind right now I don't know Capcom's marketing plans. And usually I only get a better pulse on if something's releasing soon in the weeks leading up to things happening. So this is educated speculation, but still speculation, on my side.
I do think RE9 is very likely to be revealed this year, but I think it might be revealed even later than this summer, maybe at a late year SOP or TGAs.
I'm wondering if Capcom may be bold to push Zero Remake to be revealed soon for Switch 2, but to see, just speculating.
This is just speculation on my part. I'll be very curious to see if Capcom's decided to push Zero Remake ahead first to tie into the upcoming movie & Switch 2 release, or if gonna' slate it after RE9. Really, in their ball court to decide.
I've talked about RE9 being a huge game for years. There's still plenty I don't know about RE9, but that doesn't mean I don't know anything.
Mixture of some details I know, dev ambition, & dev time (as of now, RE9 has been in dev for 7 years - longer than ANY RE game before).
Capcom's not hurting for money at all, RE9 wasn't the only RE game in dev. As I've said before, there was a very funny period in 2018 that RE:2, RE:3, RE:4, RE8 & RE9 were all in dev at once. Four of those five games have all come out during those 7 years, & sold quite well.
RE9 has taken longer than Capcom would've wanted, but there is factors to include like COVID happened, the game needed & got a delay late in dev, plus Capcom is REALLY gunning for this one to be particularly great. Just ambition takes time sometimes.
I'm going to talk facts for a second rather than speculate. So RE9 is built on the RE Tech that Dragon's Dogma 2 & Monster Hunter Wilds are using; in fact, all three of them were greenlit together to take advantage of the "Open World Dynamic Gameplay Systems" tech that was needed for DD2. RE9 started dev around the same time as DD2 & MH Wilds started dev, but it's the one longest in dev. While all three games are quite different, as each trying to innovate on their own series DNA, that might be the most decent ballpark idea to speculate on.
