Sarah's House-Season 4....where are you??

I am very anxious to see designer Sarah Richardson's work on season 4 of HGTV's Sarah's House. When will it air here in the US, I wonder??
It has already been shown in Canada, so stills of the design work are in the blog world.....I like what I see, but the best part of that show is seeing how these rooms come about, from idea boards to brainstorming, the execution of the vision is what makes up every interesting episode.
