Thanks for the feedback. We hear you.
One thing to note however is that the only team affected was the UI team.
All core hypervisor, virtual device and platform layer development remains unchanged. This includes graphics, networking, USB devices, and everything that doesn't fall explicitly under 'UI'.
Further, the old UI team is actively transitioning the code knowledge to the new team directly, it's not a matter of 'go read the docs'.
Lastly, many of the key UI developers are still with VMware working on other projects and will be able to share their expertise if the new team requires it in the future.
While we're on the topic... The new team is actually twice as large as the old and more specialized in the areas where we want Fusion to grow. We have gained support for our updated roadmap the past few weeks, and while I can't get into the details yet, we (the product team) are incredibly excited about the direction that we're taking the product in, and that direction is largely drawn with feedback from users like you and everyone else who has chimed in on this thread.
Keep it coming! We're reading everything!
