Kristian Høgsberg shared during his session on Saturday afternoon in Brussels that they are indeed planning the 1.0 release. In fact, the Wayland 1.0 stable release should be here soon. This stable (i.e. non-experimental) release is planned to be out in the first half of 2012. So before the summer, we should have a stable Wayland release where the core protocol and APIs will not be broken after that point.
Wayland 0.85 is going to be released soon (or it may be tagged now, but the FreeDesktop.org servers seem to be having issues this weekend) and will be succeeded by a series of Wayland 0.90 series release candidates. The Wayland 0.90 release will also mark the point at which the protocol / interfaces are frozen. Kristian noted though that this first stable release will not mark the point that Wayland has "world domination" for taking over the X.Org Server.
Besides these 1.0 release planning notes, there wasn't too much else of interest shared during Kristian's talk -- it was largely targeted at general Linux desktop enthusiasts. If you've read the many Wayland articles on Phoronix since I was the first to write about the promising project back in late 2008, you wouldn't have learned too much attending the talk besides these announced release plans. The tool-kit support (GTK+3, Qt 5.0, EFL, Clutter) in Wayland is coming along well, the DRI2 / KMS supportive driver configurations will play with Wayland, etc.
2012 should be an interesting year for the Wayland Display Server. For the two days prior to FOSDEM in Brussels, the many Intel OTC developers working on Wayland and other stakeholders had a meet-up to lay out some plans and discuss future work. Evidently some good progress was made there. Being discussed today at FOSDEM will be Wayland on a more technical level with learning how to write Wayland compositors and then a Wayland tool-kit Q&A.
