I hope it's OK if I consolidate these questions into one...
1. Does the battle music for Black Kyurem share the same melody as the battle music for White Kyurem? Do they use similar or different instrumentation? (similar to how in BW, the Tao Dragon trio members' (Reshiram, Zekrom, Kyurem Normal Forme) battle themes all apparently share the same melody, but use different instrumentation effects for each Pokemon...?)
I could probably just search for the song on YouTube, but I'm avoiding B2W2 music spoilers until I can actually play the game... :<
2. Regarding the Latios/Latias in the Dreamyard...is it possible for one to leave the Dreamyard without capturing said Latios/Latias, complete the game by beating the Elite 4 and Champion, and revisit the Dreamyard at a later time to "play hide-and-seek" with and subsequently catch the Latios/Latias?
3. Is one able to soft-reset for the Dreamyard's Latios/Latias? (primarily if one desires certain Natures, IVs, EVs, shinyness, etc.). Do you do this before or after "playing hide-and-seek" with it?
Thanks in advance for the answers!
