I just played the first Dino Crisis recently (Dreamcast version), and really liked it. Haven't played the sequel yet, but I'm definitely interested in #3.
Are the jetpacks new to #3, or were they introduced in #2?
Hilary at IGN has some hands-on impressions plus a bunch of new videos and pics here.
UPDATE: And here is Gamespot's hands-on article: Gamespot Dino Crisis 3 hands-on.
The vids look nice BTW.
