PvP Rewards Question

Are we going to get rewards from playing normal PvP after the season comes?

I played on RU and we were getting rewards as a result of each match, and can spend them in PvP Exchange Store for mats. Wil we get those things after the season starts?

Right now, there are in-game events for double-reward but the reward is 0, so 0x2 is 0. I cannot understand the logic behind it, any ideas?
