Yet another great popcorn thread.
That said, I haven't seen this opinion so let me offer it (and if I missed it sorry I skimmed by). Perhaps the parity in this gen is because the devs saw the sales suffering on the platform they didn't favor last gen and are now trying to keep things more even in hopes of getting maximized sales on all platforms. One vision, one game, essential one version. Backfiring, but might be in some minds there.
