Lol, I'm not sure how seriously I can take a video that said "massive large scale video game called Town"
And I don't buy that reason, nor has it really made sense to me, for one main reason,
Gamefreak are the ones who design the new pokemon, region and characters.We know from numerous interviews the studio is pretty much solely in charge of designing all the concepts for each new generation. TriggerShy created a whole thread compiling interviews on it
Pokémon designs are incredibly varied in their shapes sizes and inspirations and as a fan of the series, I'm always interested to learn about the overall process of creating Pokémon. What does Game Freak look for in a Pokémon? How do they decide where to put them? What ideas inspired them? What...

But the point is, ALL other merchandise, whether it be the TCG, toys, plushies, or the anime ALL require finalized model sheets before they can even start their work. Maybe there was a time when that wasn't the case (I remember old TCG designs having minor errors), but by now that process is probably standardized. So given that, if anything, the other groups in TPCi are at the behest of Gamefreak finishing those.
But that probably only accounts for the pre-production phase, which typically lasts on the order of months. I wouldn't be surprised if once that's done for a new generation, Gamefreak gives an estimate, based on the scope and scale of the game they have in mind, how long it'll take them to develop and the other teams coordinate around that.
I think the problems then arise because once that estimate is given, that date is probably set in stone fairly early as all the different teams have to coordinate around releasing their products around the same time,
and that's what trips Gamefreak up because they usually run up against that deadline, which they themselves probably hand a hand in deciding, and end up having issues. Another point in this favor is the fact Gamefreak, if they truly were at the behest of TPCi's deadlines and limited budget, wouldn't split their team to develop 2 games simultaneously (nor would they allow small groups of devs to develop side titles).
