From IGN:

One of the most talked about features of THQ’s WWE SmackDown series every year is always its roster. A heated topic of debate no matter who’s on it (and who isn’t), the superstar lineup is viewed by many as something that can make or break the game in an instant…. and our dedicated readers have been asking us about the latest roster situation for weeks. Luckily for them, we can confirm that this year’s character collection is one of the biggest yet seen in a wrestling game thus far — with 50 different superstars and divas in all, and an undisclosed amount of legends to be revealed later. If that sounds like a lot, that’s because it is.

As an added bonus, THQ has also confirmed the locations of its 19 different venues. Though it’s still possible that a 20th bonus arena may still be included, 19 of them are definitely making the cut. What are they you ask? Well in no particular order they are: SmackDown, RAW, Velocity, HEAT, SummerSlam, Unforgiven, No Mercy, Survivor Series, Armageddon, Royal Rumble, No Way Out, WrestleMania 21, Backlash, Judgment Day, Vengeance, The Great American Bash, New Year’s Revolution, ECW One Night Stand, and Taboo Tuesday. Sound good? Cool.

Anyhow, listed below is the complete superstar lineup for WWE SmackDown! vs. RAW 2006. It’s the same pool of characters that we’ll be pulling from starting tomorrow when we kick off our annual “SmackDown Countdown” too, so be sure and check back with us this for more then. In the meantime, enjoy this year’s crop of wrestlers and check back with us again tomorrow as we kick off the always-popular SmackDown Countdown.
