And i would gladly wait as long as possible for a game that has all pokemon with good models, much better polish and actual content over what we have now of every game feeling extremely unfinished and rushed.Because it's not feasible to create 800+ 3D models in 3-5 years. It might not even be feasible in 6-8 years. The sheer number is just not humanly possible without spending a ludicrous amount of time on them, 3D models take more time to render than 2D sprites, and we have twice as many Pokemon now as we did before the jump to 3D. That means they have 4 times the workload, maybe more.
So yes, there's no need to compromise anything.
