Some more details surrounding Apple’s upcoming TV lineup have surfaced and at this point it looks like next summer is going to be when we start seeing them on shelves. The TVs are rumored to come in two sizes to begin with, 32 and 37 inch, but after a short period there will likely be more sizes that are both larger and smaller options. Assuming Apple TV continues to sell well the entire lineup is expected to expand rapidly as well so it all depends on the initial sales results.
According to various sources Apple has already begun working on content rights to stream online through Apple TV, they have also begun working with LCD developers to begin actually manufacturing the hardware for Apple TV so it definitely looks like Apple is getting ready for final preparations for this new product.
