I created a list of all rumored Sigma DSLR lenses that are expected to be announced in 2014 (most likely at the 2014 Photokina show):
Recently Sigma released some excellent lenses like the 18-35mm f/1.8 DC HSM A and 35mm f/1.4 DG HSM A and it will be interesting to see if they can keep the momentum in 2014.
