Who Will Look Like the Bigger Fools over Xb One 2nd GPU?

[Solid-Stark]

You are missing the point. The argument changes for both sides to fit the situation. For example, if the second GPU rumor turns out false, then XBros will simply go back to "they are similar anyway, no real difference"; and if it turns out true, PSBros will say "XB1 is new cell Lulz, and difference is negligible".

Regardless of the actual fact (and arguably easy to see), neither side (or particular side) will never fully admit to it.
