Will there be a similar amount of h scenes as in Seiyuu Danshi or will there be more?
I also think there will definitely be more "H" scenes in that there are more love interests, and we just got news via twitter that at least 1 character will have 20 CG's (Moocha), so all love interests might have a bit more CG/h scene content than the Seiyuu Danshi characters.
However, I think the actual length of 1 route will be the same as Seiyuu Danshi--while there are 3 years in Banana Ranch vs Seiyuu Danshi's 1 year, they are broken up into 4 seasons rather than twelve months. So, instead of playing 12 months with 30 days each for 1 year (12 x 30 x 1 = 360 "days"), you play 4 "seasons" with 30 days each for 3 years (4 x 30 x 3 = 360 "days"), so it works out to around the same length ╮(￣▽￣)╭
