I noticed that too! I do like most of the new characters but they are getting way too much screentime, I like Arizona and Callie but their not even original characters, they are featured so heavily these days. The original interns (Alex, Cristina and Meredith) and Derek, the Chief and Bailey should be getting most screentime just because their originals. The musical ep does look good though from the previews I've watched.
