Mikami's Dino Crisis 1 is an excellent game. Dino Crisis 2 by Shu Takumi is another great entry to the series that ended with a cliffhanger ending.
Unfortunately, both Mikami and Takumi moved on to different projects after that. Mikami created the best remake ever - 'Resident Evil Remake' and Takumi created the best visual novel detective game - 'Ace Attorney'.
And with these key people not involved in the development, we got one of the worst sequels in the history of gaming - 'Dino Crisis 3'.
I doubt Capcom will ever revisit the Dino Crisis series again despite the success of first two games. However, if it happens, I hope they either reboot the series or continue from where the second game ended.
