Toki76,  The Dell Customized ESXi 6.0 ISO was just released 2 days ago. So  I would assume, from past experience, that the VIB is going to be released very shortly behind it., but as of right now I don't see it released. I can research to see if I can narrow the delivery date though, and let you know. In regards to OMSA 8, likely it will be a single version that encompassed both branches.  
Hi, is there any information on release dates for vsphere vib's for vSphere 6 (OMSA 7.4.1 / 8.0.1 / 8.0.2)  apart from that... will OMSA 8 be continued in two different development  branches for T430/R430/T530/R530/M630... and T630/R630/R730/R730xd or will there be a future single release for all 13G serversystems. kind regards Torsten
