I expect the p4p list of late 2008 early 2009 to include some of the following names.

Jorge Linares
Juan Diaz
Juan Manuel Lopez (I expect him to step up by the end of the year)
Ivan Calderon (Though he is just now entering the lime light he is over 30 so he has to hurry)
Kelly Pavlik
Miguel Cotto (As long as his chin holds up....)
