The ratings have mostly been fluctuating between a score 4 and a score of 7 since 2010. Even Best Wishes had its moments of receiving a score of 9+ :V

Considering less people are buying the newer games, it's understandable that less people would be watching the newer series. Yes XY has low ratings, but millions of people still watch it. The fate of the anime depends more on the success of the games than its ratings.
Hmm, good point regarding the above.
I will mention this, though, I'm doubtful the success of the games will have any real impact on the anime compared to the ratings, even IF the Anime is nothing more than an advertising wheel for the games now. Don't forget, DiC had animated adaptations of the Legend of Zelda, Mario, and Mega Man under its belt, yet Zelda got cancelled well before Adventure of Link, Mega Man got cancelled before we got a true adaptation of Mega Man 3, and even Mario basically ended by Super Mario World. Oh, and there's also SATAM (aka the Sonic cartoons made by DiC), which also got cancelled in rapid order. Did the cancellation of those shows have any impact on the games? Heck, no! They still managed to sell well despite cancellation with Zelda, Mario, and Sonic (and in the case of the last one, this is despite an anime adaptation that eventually floundered despite being released in the West first [Sonic X], and even has Sonic Boom coming out, plus a lot of comics by Archie Comics )actually getting new games up to the present and even Mega Man, the only one of DiC's Big 4 who at the present isn't doing comparatively well (not having a new game come out in quite some time), is nonetheless getting a debut in Super Smash Bros. and even getting his own comic serial from Archie Comics.
Besides, if Queen of the Serpentine really does have the lowest ratings out of all the episodes of AG, then I find the correlation between ratings and episode quality to be questionable.
Maybe, but on the other hand, there wasn't exactly much factors stated for why it was given such bad ratings (and in terms of the overall anime franchise, it's probably going to be eclipsed anyway).
As they said, ratings for the show don't mean much when the show is just advertising the games. Until Japan stops showing movies in theaters, there is nothing to worry about.
Yeah, and after the first XY movie turned out to be a dud (for goodness sakes, it lost to a Doraemon movie, of all things, at least according to Dogasu. I think it was the one with the blue fat cat with the googly eyes?), we've got plenty of reason to worry. I think Famon even mentioned that Pokémon's number 1 spot on its usual channel was even taken over recently as if this hadn't happened before.
And like I said above, just because the anime is advertising the games doesn't mean the games need it or that the anime is in any less danger of being cancelled, ratings loss or not. Don't forget, the 4 franchises made into DiC shows (Mario, Zelda, Sonic, and Mega Man), were meant to advertise the game franchises as well, yet when those shows were cancelled, guess what, they had absolutely no impact on the popularity and sales of the games they advertised. If those four could do it, the Pokémon franchise most certainly can as well.
