The purpose of Ultra fight has always been to maintain interest in Ultraman among the public, until a new series comes along.

They even did this during the Showa era several times, when an Ultra series wasn't on.

So think of this as filler until they heads at Tsuburya come up with an idea for a new series, or mini series etc.
