Kronin being extremely thorough and helpful yet again.
You forgot to mention that these two stages are EXCLUSIVE to the current gen (PlayStation4 and XBox One) versions (currently unknown if the PC version will have this as well).
It's anyway important to realize that the new stages and the new hairstyles (and the option for customizing the character during the selection screen) will NOT be available for X360 and Ps3 users, so keeping such characteristic an exclusive of the current generation.
Others above have mentioned they will be on PC as well.
Guess we will have to wait and see what happens then.Anyway for fairness has to be said that nothing got a confirmation so far.
Stages wont matter to the OP since he's not going next gen.Wait until the game is out and you've heard the general opinion of everyone. There really isn't much to see in LR outside of two new stages and characters plus more dlc costumes.
