One big, "Meh," from me. I'm getting rather tired of having Digital Foundry numbers as the basis for internet kerfuffles instead of the minor disappointments they are. We just went through this on Wonderful 101 for some silly reason. Games are games, not a set of benchmarks. If it does take away from the experience, by all means note it like it was in Xenoblade 2. But, no, we certainly don't "Need to talk about" Xenoblade's resolution.
It'll probably get a patch soon enough either way.
I like digital foundry but they unfortunately seem to have a very negative effect on fanboys and console wars.
