I just hope it stays as is. If they really bring Team Plasma in to the saga now, the writers would need to stall Satoshi's last 2 gym battles and the Unova League. The series would then start to drag. The reason why Team Galactic was such an important factor in DP ANIME was because they were an integral part to the history of Sinnoh. Mt coronet was a MAJOR part of the Sinnoh region and the Lake Guardians, Origin trio were all connected with Galactic. Had Galactic failed to appear in DP, the entire plot of DP would be left unglued and you wouldn't have a masterpiece. The main reason I watched DP was because of its plot and how it involved the two main characters of Pokemon(Satoshi and Hikari). The BW saga really doesn't have a plot at the moment without Plasma. I have a feeling Team Plasma MAY appear in East Unova(after the league), or wont appear at all.
This is why I love theorizing objectively using Pearlshipping as a connection to the plot of DP. With BW, I just watch it for humor ^^.
I find BW saga to be really entertaining actually, but what Im saying is that the whole DP saga gives me room to think and theorize
