I saw the new intro, today. Song-wise, I actually don't mind it, as I found it rather catchy (and getting used to a duet of singers). I like the fact it was 45 seconds, when the previous one was 31, I think. I just wish TPCI could have done what 4Kids did with the Johto League Champions OP, and hire OLM to create exclusive-for-English-dub animation, instead of clips non-stop. Oh, well.
Not their fault, per se, as the Best Wishes OP is still the one being used in Japan. I've certainly noticed how the Japanese don't update with a new OP as often as they used to, or starting with D/P. Together was, what, 70-80 episodes before High Touch, or something? The previous rate was 50-60 episodes, so things change.
Here's Bulbapedia's breakdown:

I also have to agree with Jorah's assessment, as the titles are there to basically tell apart seasons, which Japanese television doesn't really do. And I have to second gamerdna223's comment that it does sound like a TCG expansion title, which is, actually, Next Destinies. Heh. Wonder if that was intentional. Hmm.... Anyway, if anyone is interested, that's my take.
Next comment to be posted in 6 months or less. Heh.
