Upon examining the site that hosts Pokémon Origins, it appears that it's an archive of past Animé episodes, as it has "TV's" representing episodes from all of the regions that are in English so far (
not Kalos, since it has yet to be translated).
So far, Pokémon Origins is sweet.
The first episode has Brock teaching Red what it takes to be a trainer.
It also, interestingly, confirms the rumor that gym leaders choose Pokémon to battle their opponents that best matches their skill, as Brock was shown with a full team of 6 Pokémon, but only used his Geodude and Onix.
And said TM was Bide, in case you're wondering.
