Gratz on 4k!
And speaking of Team Rocket and the Latis, Ive watched the JAP version of Pokémon Heroes recently and its interesting to note that Annie and Oakley in the movie were actually not part of Team Rocket as noted in the english version. So if Team Rocket were after them again in the anime, it would probably be their first attempt.
It seems that when legendaries are involved, the lowly Jessie, James and Meowth dont contribute as much of their clumsy badness as they usually do. Such as with the main admins of Team Aqua/Magma during the clash of Kyogre and Groudon, or with Giovanni and Mewtwo. So we may see some high ranked criminal members when the Latis make their debut! ^_^;
