The biggest Bionicle set is the Kardas Dragon, which you can make by combining Axonn, Brutata and Vezon & Fenrakk. New, slightly bigger bionicle is the large 2009 Mata Nui set, clocking in just taller then Kardas.
Craigslist is a GREAT place to look for these kinds of things. I actually have Vezon and Kardas set for sale on craigslist-Charleston, SC. Check it out!
You can download them on Lego.com

It is unkown whether they're going to make another movie after this newest one, which takes place on a different planet than the one with Metru Nui and Voya Nui on it. Plus, Vezon was merely a guardian for the Mask of Life, so when it chose Matoro as its new guardian, Vezon had no more reason to exist. In short, it's unlikely.
once you defeat a boss on its stage you will pick up his mask but you have to vs vezon on a dragon don't worry he is easy. once you beat him you have completed the stage. If you go on a stage on his dungeon he will be playable.
As it is a retired LEGO set from 2006 and there are not as many being sold right now, the prices will fluctuate a lot. Set 10204 can range anywhere from $100 (opened) to $600 (unopened).
