Is it Bandai Namco or Namco Bandai Bandai Namco?
Remember when Namco Bandai (or was it Bandai Namco) changed their name? Well Tecmo Koei is doing the same thing, as their European branch is changing their title to -- wait for it -- Koei Tecmo Europe. For years it was known as "TK," which led to lots of use of the #TK hashtag, but now it's KT.
It's unknown whether or not this will be happening worldwide (it likely will be), but it's a thing. If you're confused as to why this is happening, it's because the companies are known by a certain name combination in Japan (the "new" ones like you see here), and they just wanted to make it uniform across the board.
