They cannot answer. They're under NDA.
Then we'll both have to wait
Most certainly I am not. I have better uses for 2.5 k€.
For something you have no interest in, it seems to be taking quite a lot of your attention.
The actual content of the 4.2 release remains a mystery, as well as the possible release schedule. It could be several years, and whether things like 2nd core or full 64-bit support will ever be achieved remain a mystery. All quite relevant questions considering the nature of the HW being sold. Running 32bit single core OS on such HW is much like (..reader beware: car analogy follows) buying a sportscar and disabling 3/4 of the engine.
Considering you have no idea of what 4.2 will contain or how far progressed the development of it is, your guesswork of how long it will take is basically as good as my guess i.e. worthless. I appreciate your analogy, however I don't see those restrictions being in place in the long term. My uneducated guess would be sandboxing of older apps and sacrificing backward compatibility for a new 64-bit API, multi-core, etc. Again this is just a guess. Having said that all the feedback that we have heard from people such as ClusterUK et al., as far as NDAs have allowed, is that even in your 1/4 engine state, it's still blazingly fast
I guess I've never cared about appearances, and I'm not starting now.
I'm sure your partner is delighted that you make such an effort! ;-)
Getting back on topic, I for one, will definitely try to get one in the next batch that they release. It's probably the first time since the mid 90s that I can see it being a machine I can use for my work and it's been a loooooong time since I could say that about my Amiga.
