Everyone can speculate, but I believe they are just going to stick with the classic SSK layout. This is what the community wants! I am sure they will have everything better than before too! I believe in them.
LOL. Good luck. I would be amazed to see a Unicomp SSK anytime in the next 2 years. They’ve been making totally empty promises about this for years.
Here’s what they teased last April:

So no, probably not the usual IBM SSK layout, even if they do eventually release something.
One thing I would like to see is when they release that "Tenkeyless" keyboard, they should have an actual "Tenkey" numpad to go with it.
Never going to happen. Not even worth dreaming about. If you want this, you’ll have to build it yourself.
(By the way, building it yourself is a totally possible project: you just need to cut the numpad part out of a Model M, bolt mod it, and wire up all the cut off traces to a new controller, and then hack up a case. It’s a non-trivial project, but several people have already made Franken-SSKs out of cut-down 101-key Model Ms.)
