NIcolas Cage Isn't Sure About Future Of Ghost Rider Movie

We know that Nicolas Cage is gung ho about returning to his Ghost Rider role.  We've been hearing rumblings about the sequel for a little while now.  We know the movie will be based on David Goyer's sequel script and that the movie may be set ten years after the first.
 
Cage recently spoke with MTV and he joked that there's more likely more information on the internet compared to what he knows about it.  If the movie will be set ten years later, will his character have a place in it?

“Yeah, well I don’t really know how to answer that,” Cage said when I asked if he was still attached. “Because I don’t have all the details.” 

There's always the chance that a sequel could focus on Dan Ketch rather than Johnny Blaze.  The first movie seemed to get mixed reviews with more of them leaning towards 'not liking it.'  Was the problem with the character portrayal of Johnny Blaze or were there other factors?  Could bringing in a new cast and setting be the answer?  Would you rather see the movie focus on Blaze or Ketch?
