Actually, more what I'm understanding is they had to make the models from scratch because the data couldn't be transferred over.
This doesn't mean they would look any different. It means the data was invalid. I'm not saying they couldn't have lied, but I'm aware of the issues of reusing old stuff. You can't reformat it all the time. Making it from scratch does happen. Truthfully, I'm taking their word for it that they simply had to redo the models. With that in mind, them not really making them much better could be due to a lack of time in itself. I will note that re-texturing the amount of models they need to do, even if they could reuse the models, is still a massive workload. It's not as easy as people make it sound like. Multiple game developers can vouch for how easy it is(that is, not at all).
I do agree that they should've made 'em look way better, though. Mind you, the final release isn't out. Another thing is that for the Wingull complaints, it actually moves like a real seagull and looks... accurate. Seagulls just are pretty boring in movements, that's all.
The games are going to be disappointing for many. Can't deny that. I do take issues with these accusations of laziness and incompetence, though. That's vastly unfair and harsh. They're still working very hard. Now, I do agree it sucks that Gamefreak and The Pokemon Company should not be making it so hard to work together and should spread out their releases for stuff far more. So that is a bad thing on their part.
Last thing to say is their transfer methods were pretty dumb, forcing you to pay money for Pokemon Bank(or similar substitutes in earlier generations). Mind you, at least it made sense for Stadium since it cannot be a downloaded game. But once the 3DS rolled around, Bank should've stayed free.
That should cover everything. I prefer to take companies at their word as long as they're honest(so far they have been). I'm giving them the benefit of the doubt. I'm a game developer myself and I've had immense trouble working on stuff, so I can feel what it means that it's not easy at all. It's also why I find the accusations of lazy and incompetence vastly unfair and uncalled for. There's no reason for that.
