So far the WSL SIGGRAPH 2017 guessing game has already listed most of the things I could reasonably expect to find in a shiny new copy of Fusion 9.
I hope I'm not spoiling my ballot but I'd like to try something different and make my WSL SIGGRAPH guessing game entry a long distance moon shot at guessing what we could expect to see happening at SIGGRAPH 2018.
I think Fusion X will launch at SIGGRAPH 2018 and we can expect to see the addition of a new OpenEXR deep compositing toolset including a module for deep data based bokeh simulation. macOS users will be able to buy Fusion X in the Mac App Store.
On the same day at SIGGRAPH 2018 the Foundry will have a surprise announcement that the unprecedented success and popularity of their Elara cloud platform means that it is now time to end the sale of permanent Nuke/NukeX licenses and go for a 100% subscription platform offering. They will say that customers prefer the convenience and affordability of Foundry maintenance plans without having to pay the large upfront cost of needing to buy Nuke first. Also I think by SIGGRAPH 2018 the Foundry's CaraVR toolset will likely be added "free" as a bundled item that ships with every copy of NukeX.
Again. This is my 403 days away entry for the WSL SIGGRAPH 2018 guessing game contest.
