I've seen some comparisons where the New 3DS XL is longer and then some where it is basically the same size... makes no sense.

I cannot find New 3DS XL cases so I'm guessing it is the same size? Is the US/EU version slightly bigger than the Japanese/Aus version?

Thanx.

The new 3DS XL is literally about half a millimeter smaller than the old 3DS XL. What do you think?

What Falcon said, it's pretty much the same exact size.

It's a fair question, sometimes they redesign the dimensions just enough that old stuff randomly doesn't fit it anymore.
