For years Technics had tried to exercise similar control over their keyboards' prices, with no discounting, no mailorder sales allowed (at least here in North America). Despite having a great product, they folded, because they were too greedy.
I don't think they will be following the same sales model here in the US.
Without meaning to start an argument about the pitfalls of the 30-day return policy, I will say that there is no substitute to being able to try an instrument yourself, without anyone peering over the shoulder, and other customers rushing you. I usually don't return my purchases back to the Guitar Center, but on occasion I do find that whatever I bought was not suitable for my needs. Having the comfort of a 30-day return is a huge motivator in buying things from them. Roland will be losing sales fast if they switch to this.
This is my $0.02 worth.
