Those previews for PPGZ were....interesting.... so they transform ala Sailor Moon???
As for Vegeta.... he may be an ass at times but he's got a soft side....he's a bit like Raphael.... tough exterior and a hot head, yet on the inside he loves his family and would do anything for em. Meh...I just think he's hot...*shrugs*.... I know other peeps who think that about Vegeta as well.....
