Sorry, but that is incorrect Star Wars: The Clone Wars is the name of the new animated TV show from Lucas Animation (Part of the Lucas group of companies that include Skywalker Sound and ILM) the Wikipedia entry for which is
here.
What you are referring to is that the first three episodes may, and I repeat may be joined together and released in theaters as a feature with the rest been shown in its weekly format on TV: which from what I've read should be this fail, but at time of writing this they don't yet have either a channel to broadcast on (its home station as it where) nor do they have syndication in place for international broadcast. According to Rick McCallum the producer on the Star Wars franchise including Star Wars: The Clone Wars release in theaters for the first episode is one of a number of options that are been considered, but as yet nothing definite has been decided.
As to releasing Star Wars in 3D Gorge Lucas has stated that this would only happen when enough theaters are equipped with the technology, other wise it won't happen until that time.
Regards to you.
