This article is conformation of a rumour that a new Halo title will be unveiled at E3. CVG arent the only ones confirming the rumour either. I found out about this whilst watching the news programme on Pulse gaming channel this morning in the UK. Althiugh Pulse said rather than Halo 4 being unveiled, It was looking like Peter Jacksons Halo Chronicles will be there to steal the show.
Their sources said if MGS4 is looked at as the start of fusing cinema and gaming together then Halo Chronicles certainly perfects it. They confirmed ( although we should take with a pinch of salt till E3) that the same cgi and graphics team that workd on LOTR trilogy films and the Halo 3 trailer below are working on the graphics. And with world reknowned Director Peter Jackson doing the entire dialogue and cutscenes himself, without a doubt will be a fusion to behold. Lastly they mentioned that the source had said it is heavily cutscened like MGS4. So will probably be more for fans, although Peter Jackson is obviously are far better director than Kojima.
Remeber none of this can be entirely believed till E3 has been and gone. Obviously there is alot of sources popping up with info now CVG, Sarc gamer and Pulse so it's looking more true.
