Will Pokemon X/Y be the best games in the series so far? I hope so and given what we've seen so far, I believe it could be a real possibility.
In response to your first point, I totally agree. Pokemon is the best monster-related series to exist. However, I must point out that when you said "it's better then Tamagotchi and definitely better then Digimon" you made it sound as if Tamagotchi was actually in some way better then Digimon. Obviously this was a mistake on your part seeing as it is a well known, scientifically proven fact that the first three seasons of Digimon (seasons 1,2 and Tamers) were far superior to even the Pokemon anime.
Now your second point about the Pokemon anime constantly getting better. Again, I am inclined to agree with you. Ever since the debut of Black and White I have been watching the Anime and quite enjoying it. I am really looking forward to Ash's adventures in the Kalos region
No game has been worse then the previous one. At most the worst problem was not enough changed or there was new balance problems, but not enough to make the game worse then the previous one.
The B&W anime while graphically superior, is pretty terrible in my opinion. Mostly because I don't care about Iris and Cilan, but some of the side characters are pretty good. The "Team Rocket are not idiots" parts was okay.
