How much would it cost to port AmigaOS to x64?

No valid reason for OS4 to go to commodity hardware.  The market isn't there - niche OS's are free/open source on commodity hardware, Hyperion would have no business model.

It's be just another offshoot hobby OS that could once make a meager earning on the PPC side that is now on commodity HW where there's a plethora of free OS'es for every niche market.  Another OS I'd have to run an emulation layer on to run legacy software.  Why should I run OS4 x86 vs. AROS, vs. UAE/Amikit/Amithlon?

There is also the fact a small team could never support the vast range of PC hardware.  This is the same problem that hampers AROS.  A small team cannot support every chip made for a mobo, or every gfx card released in the last 10 years.  The same reason Apple locks hardware to software - no ****ty coded 3rd party drivers on core HW.  Same reason MS doesn't do drivers themselves and why they have WHQL.

I'd love to run AROS, but it simply doesn't run on the hardware I own.  AROS for SAM 440 is absolutely unfunctional.  That being said, I don't expect a hobby OS to support my dual 590 GTX's.  Either would OS4.

Now OS4 for PPC Mac, that's something I could go to bat for.

AmigaOS on a gaming console would do nothing for anyone, tbh - and the thought of it ever happening is even more foreign than the concept of winning the lottery as per the OP's post.

Sorry - MS, Sony, or Nintendo aren't chomping at the bit to get their hands on a niche OS that only old guys and turbonerds care about anymore, lol.
I love the Amiga, but I'm not delusional that I think it's even a blip on the radar to modern computer users.

There's a difference between optimism and enthusiasm, which is a sort of a "what if?  that would be neat!" concept, and actual real world realism that something if ultimately practical.

I use the comparison of Amiga emulators on mobile devices.  Neat for 5 minutes, then the practicality of it kicks in and it is realized that practicality wins out.  I'm all for doing things just to see if they can be done, but in the end most things are just novelties, IMHO.
