UPDATE (11/9/14, 6:30 p.m.): Amusement Buzz posted a photo of the current park map, which confirms this change. Starting today (November 9, 2014), Universal Studios Florida started using the new parade route, which is represented by the red line on the above image.
While the Superstar Parade does seem to have this new route, the Holiday parade has used this route for years but it starts and ends at San Francisco heading towards Cafe La Bamba and looping around with the last float with Santa stopping near the Mummy and doing the tree lighting ceremony.
Not sure why the Superstar Parade is using this new format. It might be a way to get TM's prepared for the new Holiday layout or it could be something larger. Honestly, I don't see the point in expanding the parade route unless more floats will be added. It never seems like a popular parade even during the summer. It's extremely easy to get a curb side spot the moment the parade is passing so expanding it to make more room for guests doesn't make much sense.
However, an expanded nighttime show would be awesome! They need to greatly expand the number of fountains and include more fireworks. They have a great chance to create a real "World of Color" size show with thousands of fountains before Disney has the chance to open their AK show that seems to be an expanded World of Color.
