IMHO, wide & ultra-wide lenses, and good cheap wide (<50mm) primes.
Considering Canon just entered the cinema camera & lenses business, and therefore would probably invest R&D resources in developing lenses for those, I wouldn't expect much news in the DSLR lenses market.
[OK, some of the cinema lens designs might leak into the DSLR market, but - as noted - those cover APS-C sensors, I guess any such lenses would be EF-S.]
