I feel that you're looking at things the wrong way. Let's take a look at how a business works:
Gamefreak has been selling Pokemon for nearly what, almost 20 years? Give or take. Throughout those 20 years, they've tried many formulas, they've implemented many things. Some resonated with fans, some didn't, and that's honestly how it's going to be. You're still going to buy it right? Then as long as you, the customer, are buying the games, what's there for GF to worry about? Pokemon games these days are selling by the millions, and it's literally ridiculous to see how much they're flying off the shelves. I'd say GF is far, far, far from being anywhere near bankrupt or "collapsing on itself" as you seem to imply, because as long as the game keeps making them rich, they will keep designing more Pokemon, and they will keep shelving out Pokemon games until they no longer make money from it.
If you decide not to buy it, then that is your choice. However, bluntly speaking, you are only one person out of the millions of Pokemon fans that might purchase the games and give GF the revenue it needs to make more Pokemon games. That only proves that the company is being successful, not that anything negative is occurring.
I'd say nothing is happening too fast, either. BW2 is done for; whether you had your chance to play through Unova or not, GF will move on as it sees fit. Also, take note that Pokemon Conquest is a spin-off game, and take note that spinoffs are usually much, much shorter than their main-game counterparts. I remember beating Conquest in a relatively short period of time (about a few days, give or take?) and then kind of put it down afterwards. I mean, I assume GF knew that this whole time; and just shoved out Pokemon Conquest to keep fans entertained while they continued working on other projects that they had, like Pokemon X and Y.
I feel that this is the most logical guess to what went on, but that's just my perspective. I think you're jumping to conclusions a bit about how it can collapse upon itself, when it's doing extremely successful so far.
