They're not saying that it sucks, they said it was on par with current hardware. Everyone knows it's going to be more powerful than current gen, that's not the point of contention here - it's by how much, and this latest statement sheds some light on that.
It sheds fuck all unless you intentionally want to stick to one vague comment and ignore a ton of other vague comments. If it's so obvious that the wii u is more powerful than this gen, what the fuck does "on par" even mean. Nothing. It means fucking nothing.
Because the two ideas, Wii U being superior than this generation and being on par, are categorically in conflict with one another, all it shows is that there is a level of imprecision when it comes to these developer comments. Just like previous dev comments talking about Wii U games with better resolution, more ram, larger textures, being a "stop-gap," being the most powerful console on the market at launch, etc. they're all vague and imprecise statements that were never meant to be taken as a bullet point to be used in any sort of tech-war argument.
For all we know, the guy at vigil who made that statement was simply meaning to say the dev team is
targeting a wii u build that's "on par," meaning they wont be attempting to make any visual improvements at all. Keep in mind,
just because I say this is a possibility does not mean I subscribe to it as fact or am purposefully deluding myself into thinking that's what he meant. "On par" could mean a lot of things to a lot of people. It could mean current gen games at 1080p at 60fps. Or it could mean being identical to current gen games. The problem here is that
everyone who is sure of one argument over another is cherry picking the quotes that they like and interpreting them in a way that supports their predetermined conclusion.
