We have no info on ORAS except that it's releasing in November and it's going to include Kyogre and Groudon. In other words, how are we supposed to know? --- "A delayed game is eventually good, a bad game is bad forever." -Shigeru Miyamoto
if I had to guess, probably. gen 3 didn't have a day/night cycle due to limitations, not because hoenn and kanto are in perpetual daylight. --- 3DS Friend Code: 5413-0006-7792 PM me so I can add you as well!
