Considering the glacial pace of modern AAA game development, I don’t think it’s odd that they want multiple games in development at the same time to ensure a steady release schedule.
We don’t really know what these five games are (if they really exist at all), but if they diversify the offer with a mix of first person, third person, remakes of old titles and maybe yet-another-attempt-at-bad-online-RE-that-nobody-wants, which is what they’ve done so far (RE7, RE2make, RE3make, Resistance, RE8, RE4make), I think it’s a good thing.
