This lineup doesn't excite me too much. Anthrax are good, but they tour North America often. Sabaton is a similar case, though they are definitely the best announcement for me. I can't go anyways, but I'm going to be following the announcements to see how it stacks up.
Also, for whoever said they don't have good lineups anymore, look at 2010 and 2011; both are completely insane lineups. Even this year's lineup was pretty strong, it was only the headliners that were weak.
The size shouldn't be a deterrant. With the exception of Scorpions, I could get as close as I wanted for every band and could see the stage and screens for all of them. For the bands in the Bullhead City Circus (W.E.T./Headbanger Stages) I was either on the rail, or could have been on the rail but chose to stand further back. For the main stages, you could also get extremely close, and probably even get to the rail if you really wanted to.
