Yeah, no info. There was some supposedly leaked roadmap which featured a "Haswell Refresh" at Q2 2014 and Broadwell at Q4 2014 launched alongside Chipset 9 motherboards, which kinda implies that Intel may chose to screw Chipset 8 out of Broadwell support.
Though that's not a concern for I7 owners, it's more of a concern for lower end I5 and I3 owners who hoped to upgrade to Broadwell.
Or, it could be fake and I'm spreading misinformation
