Sora still exists. Like any mfg companies, products are often pushed down stream when a new one comes up (rebadged). So the current 2200 stuff were old Soras and Sora were old Tiagras. I don't know if Ultegra or Dura Ace get rebadged into Tiagras. I only know the downstream march of Tiagra, Sora and 2200 stuff. This is nothing new in the world of product companies. Xenon lights used to be exclusive to high-end cars, now even a lowly Mazda3 sport has em... and it swivels too!
