Yeah Fungus, it will sadly not be cheap, it looks to be a revised flagship
Micsig seems to be somewhat tight about it, but at least it ain't just a render - and is a model under development headed to market.
Micsig refers to it as a "500MHz, 3GS/s scope".. if the 500MHz is entry-model bandwidth, I don't know.
It does seem to have resonated with Micsig, that people prefer knobs, no matter how intuitive & touchy' you make the interface on these dual-purpose scopes (mobility & bench-use)
Both Micsig's relatively new models TO (10") & ETO (14") are completely removed for UI-buttons and their newer revision of "STO" line (8") is based around a 4-way joystick interface - with a somewhat minimalized button-layout (19 buttons & 4 joysticks) quite a bit less, than the quite popular STO-C/E series. with 23 buttons & 7-clickable rotary knobs.

My guess is that it's this 14" ETO-flagship model (500MHz, 3GS/s) that is present on the Chinese market, that is now being retrofitted with knobs & button interface, and the specs from the [ETO5004], would likely go a long way in getting an idea of this new model fundamentals.
