i'm pretty new to the world of projectors. i'm not looking to purchase until may, which will be when my home will be finished. i see that panasonic and sanyo are upgrading models, and their current models (z3 and ae700) are right in my price range. how long do you think these projectors will be on the market, and how much of a price drop can i expect on the new models over the next 6-8 months. i guess i'm wondering if i should purchase the older models right now in case they are discontinued, or if i can wait.
