Amiga poll about after OS 3.5

All Amigans have questions about their Amiga future. We want to know what we'll have after OS3.5. Those questions have been sent to Amiga Inc, to Lisa Matherne, Executive Assistant to Jim Collas. Here is the answer I received :
I have forwarded your mail to our German office. They can better help answer your questions.
Darreck Lisle.

Questions are:
- Is it possible to plan a new OS version WITH updated ROM chips this time ?
- Is a multithreaded WorkBench could be done in such a release ?
- Can we have PPC version of parts of the OS as applicable ?
- On what depends AmigaOS releases further from 3.5? Sales volume?
- Are RTG and RTA abandonned ? Released in next versions ?
- WarpUP is in, when will we have Warp3D?
- Have you considered creating a new RTG system, more adequate to your own video API, and potentially more stable as a patch to the original AmigaOS graphics libraries ?
- With RTG and RTA, the next step towards a much needed hardware independency is 68k independency. Will the PowerPC 68k emulator make it in future releases ?
- Can the emulator be a form of integration of protected memory, or at least a way of recovering the rest of tasks, when an application goes belly up? In this case, if virtualization of the whole CPU is a form of protection (taken in the broad sense, something like Java), the Real Amiga could happily stay using old 68k binaries forever (of course, software should go PowerPC), at some decent emulation speeds provided by modern hardware.
- Then... AmigaOS 4.0 for PowerUP, PowerPC and x86 ?
- What about the 68k emulator by Sam Jordan ? in page http://home3.swipnet.se/~w-32234/ppcrulez/news/sep98.html, it's written that this emulator works. Where is it ?
- As next OS versions will have PPC support, do you think there is a chance to see Amigas sold again with PPC chips only ?
- What do you think about a free AmigaOS (Open Source) ?
- Will next versions have some Workbench enhancement: pop up menus, sensitive menus, user definable menus, many shortcuts ?
- What about "Themes" (with different sounds,backgrounds,icons and window styles) ?
- Any shell enhancement planned (kingcon...) ? A command interpreter update (not only the console device) so that it can handle command lines longer than 511 characters...
