In my opinion, AmigaOS 4 is not dead as long as people are using and enjoying it, whether it is on dedicated hardware or through emulation. I'm definitely not going to stop with this hobby just because it is available through QEMU as well.
I'm happy for those who can finally experience it properly without having to pay a huge admission fee. I believe this will bring us new users, who eventually will want to get hold of dedicated hardware. If not, I'm sure some will buy games and software from AmiStore, Alinea, Amedia and so forth.
That AmigaOS 4 is dead has been said for ages now, which is one of the reasons I started writing the AmigaOS 4 Monthly Round-up series. When one looks a bit around, there is plenty of activity, enthusiasm and hopes for what the future can bring. I don't think this will decline with QEMU. I might be wrong of course, this is just my personal view on the situation.
In the end, it is us, the community of AmigaOS 4 enthusiasts, developers and users, that IS the platform. As long as we continue enjoying it, it will continue to live on.
As for the A1222+, yes it is very expensive. A motherboard costs more than the Sam460, but you do get Enhancer, AmigaOS 4 and all the latest graphics drivers included, which costs quite a bit to purchase. If one buys the Sam460, you must pay separately for those (except for AmigaOS 4).
Now, here is an idea (which may be unfeasible, but I'll share it anyhow) I've had pondering this.
One success in the past was the brilliant FlowerPot tool from AmiKit, which made installing and setting up AmigaOS 4 through emulation (WinUAE)on a regular PC very easy.

I've used it myself several times and it makes it (almost) hassle free to get started with AmigaOS 4.
Maybe such an approach, only with QEMU and the other stuff, could be something A-EON could consider, or possibly get AmiKit on board to make an AmigaOS 4 QEMU-edition of FlowerPot? It would certainly make the threshold for potential new users and developers much smaller. Let us say this FlowerPot version would set everything up for you during the install and you could for example choose which system to emulate and so forth.
That said, I've never used QEMU and I do not know how hard it is to set it up, but shouldn't it be possible through a good script setting all up?
During the install process one could get an option at the end of turning on "Start AmigaOS 4 directly at boot-up every time" or not.
Consider KX Light from Amiga Forever, which starts the environment directly at bootup on the PC, hiding the minimal host OS in the background.
Sorry for long post, but had a lot on my heart concerning this.
