Sci-fi coasters in the dark with no loops and a light show for scenery - it goes deeper, actually - heavy emphasis on blue lighting, starts in tunnel with mirrors and flashing lights, ends in a tunnel with pulsing lights, etc.
Watch the Shanghai video - even the loading area is very, very similar to DL's SM. Tron is much, much more like SM then Shanghai Pirates is like our Pirates.
Plus, we have Tron Track.
Basically, the only way this makes sense is to think of it in terms of TSMM adding another track or Soarin' another theater. Desperation for capacity without concern for thematic coherence (it doesn't match with SM's architecture at all) or uniqueness.
