Personally, I don't think it's going to top ORAS. The inclusion of the renewed Battle Frontier on top of porting the PWT with full BW2 soundtrack was absolute kino. Sucks that the entry to Driftveil is blocked off, but I guess they couldn't exactly put the entirety of Unova in on top.
I will say though, Primal Palkia and Mega Giratina had me awestruck.
