It appears that the rumors about a new Sigma 135mm f/1.8 Art lens are back again (they have been going on since 2013). A new fast 135mm prime would make sense as this focal length will complete the current line of Sigma Art lenses:
The other rumored Sigma Art lens is a new 24-70mm f/2.8 that could be announced for the CP+ show later this month.
As CanonRumors already suggested, if there will also be a third new Sigma 14mm f/1.8 Art lens, it will most likely be APS-C based, a full frame 14mm f/1.8 is just going to be too big - the Zeiss 15mm f/2.8 lens for example is almost 2 lb (over 800 g):
