Silverlight Memory Profiling Roadmap?

I've heard and read many times that Jetbrains offers (or will be offering) a Silverlight memory profiler.  dotTrace seems to be undergoing a significant rebranding with version 4.0 - i.e. breaking out into a Performance edition and I'm assuming a Memory edition? Reading through the homepage for dotTrace 4.0 is a bit misleading.  One would think Silverlight memory profiling is available, but as far as I can tell it's not.

Can you give me an idea of when this tooling will be available?

This is asking the same thing, but has gone unanswered:  http://devnet.jetbrains.net/message/5263281#5263281

This seems to suggest its available in SL, but it's almost a year old and seems to be talking about SL3:  http://devnet.jetbrains.net/message/5245219#5245219

We would very much to purchase this tool the moment it's brought into existence :)
