I know a lot of people probably don't care about it, but I really want a feature where when you pause during a match (Offline), the camera will be able to be controlled, so that you can view the stage, characters, etc. in a 3d type perspective, and take pictures for your XMB.
If possible by patch, maybe a ''cinema'' type thing like Uncharted 3 has, where you can review a clip from a previous game, record a certain part of it, and upload it straight ot Youtube. Allowing you to also be able to take pictures of the fighters during the cinema, so you can save them for later usage.
Maybe it's just me, but I would really like it. It'd also give the forums something extra to do, like uploading pictures of ranked match results, or something silly/stupid/infuriating that happened during the match, or maybe just for fun.
