The tech publication CHW.net claims that it has confirmed the release of BDW-S and even BDW-K in a few weeks.
A recent roadmap showed showing BDW-K but no BDW-S in Q2 2015 but CHW found that ASUS has listed support of 5th generation processors on the main spec sheets of various Z97 motherboards.
This might be a little weak evidence. The specification of 5th generation support has been there for a long time and axing the chip has been a more recent decision.
The ASUS spec also mentions Broadwell-S too, something which has been dropped from the roadmap for ages.
But it is interesting because if BDW-S actually releases, it would mean that the launch of Skylake-S might be delayed a bit further, to allow Intel to make money on it.
