Poland too? Wow, I guess I have to give the dollar more credit then (pun intended).
I hated moving around as a kid. Once I finally got settled in one place, we ended up moving to another. I've lived in 5 different states and a few countries. Once you get to the point in your life where you want to start a family, remember that they're affected by it just as much, if not more than you are.
Oh, so youre going to France for this? Thats cool. I havent been to France since I was about a year old. The first time is the hardest, at least thats what the instructor told me (I took a beginner's class so I would at least know what I was doing). When I came back, literally my entire body was covered in bruises. It was painful, but well worth it. I might be going again in a few weeks.
Most prediction is tough to begin with, the reason why its "difficult" because the same sets are mostly used in comp play. Not only that, but his special set isn't even that good. They are more than likely be physical
I know you were talking about why they don't have MEs for ALL Pokemon, but you took the fact that we don't have 3D models for all trainers as the hint (the 'why') that Game Freak must be limited to a maximum of 28 Megas this gen. I don't even consider having trainer 3D models as a pre-requisite for adding Megas. It's like how Game Freak could probably finish adding evolutions for every single stage non-legendary but they never had the intention to, and instead constantly add more single stages for every new generation to leave things open. Likewise for Megas, even if Game Freak accelerates the process a little such that we can eventually have Megas for every Pokemon over the next few generations, they won't do it. Whether we get 3D NPC trainers is a mutually exclusive issue altogether.
As for how Megas would exclude the addition of Cross-Gen Pokes later down the line, that's anyone's guess. Megas aren't permanent upgrades, and there's always a small chance that cross-gens can still be added as a branch from Mega. If not, I guess some unfortunate critters with unimpressive megas probably have their fates sealed.
