Hi David Clay & Benoit_Fournier. I hear you both about dates. I don't have further insights to share beyond the fact that our goal going into SPC18 was primarily to show only those things that will land in Targeted Release before Ignite 2018; barring things like #SharePoint spaces where we were a little more explicit. We'll ensure to make the right communications go out as we move to send message center posts to admins and targeted blogs with greater detail closer to roll out of each feature, or related set of features.
Our intranet partners will always compliment what we offer in the pattern of offering that which we don't yet offer. It's not a terrible thing to get started with a set of projects that do and do not require partners, to set the stage for a real deployment where many sites can be OOTB, or require partner solutions for others, or possibly even still custom sites that leverage the classic SharePoint publishing infrastructure. We will move as fast as we can to deliver what we'v disclosed, and rest assured two thing, 1) we'll keep that pace with future disclosures and news twice a year :-), and 2) our partners will always add value on top where you need it.
Hope that helps,
Mark
