Should be a bare HOF the next few years. Big Hurt next year, Randy Johnson in 2015 and Griffey in 2016 are the only first ballots I can think of. Biggio and Piazza will get in within the next couple years.
Probably more than you realize. Saw a list of some of the new candidates for the next few years:
2014: Moises Alou, Armando Benitez, Sean Casey, Jose Cruz Jr, Ray Durham, Damion Easley, Keith Foulke, Eric Gagne, Tom Glavine, Luis Gonzalez, Scott Hatteberg, Jacque Jones, Todd Jones, Jeff Kent, Jon Lieber, Esteban Loaiza, Paul LoDuca, Greg Maddux, Matt Morris, Mike Mussina, Trot Nixon, Hideo Nomo, Jay Payton, Kenny Rogers, Richie Sexson, J.T. Snow, Shannon Stewart, Frank Thomas, Mike Timlin, Steve Trachsel, Jose Vidro.
2015: John Smoltz, Pedro Martinez, Carlos Delgado, Gary Sheffield, Cliff Floyd eligible 2016: Trevor Hoffman, Billy Wagner.
Obviously far from a complete list for 2015/2016. This is just what I saw Adam Rubin tweet earlier. Assuming Maddux, Glavine, and Frank Thomas get in next year. Assume Smoltz does in 2015. I think Pedro should without any doubt, but I just never know when these writers/voters want to make it all about them.
