I have a soft spot for 5 as it was my first RE game. I remember playing couch co-op with my best friend growing up. But personally I can't wait for 9!
First person really suits the RE world. 7 scared the sh*t outta me, and I couldn't stop playing 8 when it came out. I must've played it 6 or 7 times in a row because I couldn't get enough of it.
I hope 9 is next, and they keep the direction they've been going. But I'd love to bring back couch co-op with the Resi 5 Remake.
