Okay, this could be the biggest UT tease in a while but Ice.T on the Epic forums spotted THIS on a Swedish game site. It lists a new UT as coming in 2015 for the Playstation 4. You will need to use your browser to translate if Swedish is not your native language.
I’m going to take this as complete BS but…if it does happen in 2015, I guess I still have plenty of time left to finish my UT3 maps :). Tantalizing thought though to have a shiny new UE4 editor with a new UT!
