I mean I see a lot of people talking about him retiring or something. I honestly think that this rock band thing might just be a side project or something experimental for him. I don't think he's done rapping for good though. We just might not see a Cudi rap album until like, 2012. I mean he is still doing GOOD Fridays with 'Ye.
Cudi might just transform his style into more of an R&B type thing too.
