Ya, SAKL has a failed past, hard to read what is in their plans with it to turn that around and I am not planning on putting any $$$ to risk a Sack Lunch.
When it comes to possible renewed plans with RBSY, I would say it has the best chance of new developments and seated to be used with the connecting companies (SAKL, CGRW & SGDH) plus maybe other companies to pick up RBSY contracts/product.
Interesting times started with RBSY back in May of 2020 when volume buys came in out of nowhere and over a year later still gets spikes in buying.
I would say we are getting closer to knowing if RBSY is something or not!
