Pokemon: best wishes

Seven episodes of the Pokemon: Best Wishes anime series has already aired in Japan and Satoshi has almost a full pokemon team already. Along with a almost complete team Satoshi has earn his first Gym badge in Isshu. I will say this I'm enjoying that this new pokemon series has less fillers than previous series. I wonder what pokemon will be Satoshi's sixth pokomon. there is a rumor going around that he might catch a Koaruhie in episode 20 of the anime. But that won't be confirmed until the episode airs.
