http://youtube.com/watch?v=otspzrILEA4 i hear its only for Xbox 360 And PS3(wish i had one =()i HAVE to hate Goku's jap voice...(i hate EVERY jap voice no matter WHAT!)kidna the same as Budokai 3 but more graphics but ...no Super Saiyan 3 or 4 OR FUSION! =(..i think thats what the ppl say...
EDIT:the game is out already.... Game Release: Dragon Ball Z: Burst Limit (US, 06/10/08)
and the game has online play
Gameplay? same as Budokai
Story?:....well some of the storylines are missing..i got this at gamfaqs look: Although fighting games usually aren't known for their stories It's always nice to replay the epic battles of the storyline with cut scenes and a dynamic presentation. Did Burst Limit succeed in this endeavor? Well yes and no. First of all the Buu saga is missing in this game. So none of the new characters and transformations are present in the game. Which is somewhat disappointing. Having a next gen DBZ game and not even including the entire story.
The next issue with the story is that it jumps around a lot. If you are new to DBZ you will have NO IDEA what is going on. Some battles just feel like they are thrown in there while other battles get a huge cut scene and an epic presentation. For example the final between Goku and Freiza is absolutely amazing and the cut scenes that go along with the fight are spot on in delivering the feel of the show. However this fight is one of the few exceptions. Most battles don't have this and many key parts of the plot are missing.
Also the campaign is short and can be easily finished in one sitting. Including the what if sections. Its short and sweet I suppose you could say. Drama pieces also do a good job of playing out key parts of the battles. Characters getting angry during major battles and missed attacks that were a major part of the battle in the show.
Voices?:you can choose to English to Jap (i recommen(damn spelling) English since goku's voice in jap sucks cz goku is voiced by a jap woman YES YOU HEARD ME A WOMAN!)
EDIT 2:http://www.youtube.com/watch?v=7ipObsdRSNg found the English one! thats better!
