I really liked RSE for having 2 rivals, but it bothered me one was some random person and the other was the opposite player character. That was strange to me. At least this time its two random people. Instead of half and half. Consistency, man.
By the way, who else noticed that at 3:00-3:05 in the video, and again at 3:19-3:25, the music seemed very familiar? ...I figured out that it was nearly identical to a section of the R/S/E Team Magma/Aqua Leader battle music! It transitioned to a different melody in-between, but it was the same tune and rhythm as 0:51 in the Magma/Aqua Leader song: http://www.youtube.com/watch?v=SRsUBDLTrZ0
Are these coincidences hints at Ruby and Sapphire remakes coming down the pipeline? Lots of similar stuff happened in Diamond/Pearl that pointed to the eventual HeartGold/SoulSilver.
I know this is Black and White speculation, but when we have a 'pattern' like we have established, these hints seem related.
