I don't think there's anything definitive on either broadwell for desktops or skylake yet. Some said broadwell would come to lga 1150, others said no that because intel pushed back broadwell and opted not to push back skylake (the two will release very closely to one another) that broadwell would only be available on lga2011v3. From some articles I've read intel didn't even want to mess with broadwell and wanted to skip it entirely.
Another thing to consider, the skylakes that are coming out along with the new socket 1151 will be the second half of 2015 (3rd or 4th qtr supposedly) and will be the non k variety. Unlocked k edition skylakes are rumored to be somewhere around 1st or 2nd qtr of 2016. Take this all with a HUGE grain of salt because it's been nothing but speculation and rumors and there's been no definite answers on any of it yet. Regardless of the tech site, no one has the real scoop because intel hasn't come out and said for sure.
