Most car audio manufactures introduce their new models at the Consumer Electronics Show which occurs every January (Google 2010 CES) and they usually start hitting the stores around Feb – March. Some models get replaced, while others get carried over unchanged. I believe the Pioneer 800bt will be carried over through 2010. I like the Pioneer AVH-P3200DVD myself.
