Springfield heighs part 3?

Do you think we will ever see a new SH update? With more land and buildings? I know we already have tons of currencies but i remember there was an unreleased sushi currency for SH. So maybe we could have a new fancy sushi resturant generating this currency (maybe with the master sushi chef as character...), and, i guess, a new monorail SH station will fit perfectly as new building because it would be upgradable like the other stations and like the other SH buildings. This could be a cool upgrade, what's your opinion?
