I don't really see it. Basically it's the same in terms of ratios as Sounds of the Underground. It has like 2.5 times the bands, so it has 2.5 times the good bands, and 2.5 times the crappy bands. So you end of with a bunch of -core crap, a few mediocre metal bands, and a few great bands. Cryptopsy is also at Maryland Deathfest, and that wins anyway just because they have Wormed there, who wouldn't be here any other way. Then you've got Pig Destroyer, Aborted, Impaled (and Ghoul), etc. The fact that it's death metal and not metal and hardcore (which means lots of -core), generally means it will be better anyway. Unless you like -core, of course.
Oh, and wouldn't Nightwish's tour cancellation cancel this festival date as well or something?
