I think where a change would be welcomed, the true matter is, what to?
The problem is, we're so use to the WWE logo that where the scratch look was that of the attitude era, when the logo changed to WWE, it represented an era change entirely, now it's overly used that changing it would be pointless, does McDonalds, Pizza Hut, Burger King, etc change their logo? More that they kept and fine tuned it because that's how recognition of a company comes, through the logo.
I think if they changed the logo to read WWE, it would look shit! The WWF logo was just right, nicely done, the WW that WWE use for the current logo is a much tidier version of that logo. It won't really go, I can't see why they would given the whole WWF lawsuit with the pandas, the effort to change the logo again? Give another 10 years maybe, but not now.
