Amazon has just put up a pre-order for "Rita Rocks - The Complete Season 1". The release date is April 27th, 2010 and the list price is $18.99.
The description says that it is a 3-disc box set that will include bonus features.
I sent an email over to TV Shows on DVD to see if they could confirm it. They said that it is in fact coming out, but since it really isn't in demand, they have yet to post the listing.
In any case, it's good news that we will get to own Season 1! Here's the link to the Amazon page:
