If it gets the same user interface as the other touchscreen models before, then it's not bad.
However, it would be better for the screen size if it went more in the direction of the rigol UI.
There you have almost everything relevant at a glance.
It will be better in terms of features and technical data, it just depends on the price that siglent wants for it.
Just some notes.
SDS800X HD have same UI as SDS1000X HD, touch and mouse. Exception is display physical dimensions.
(also much same as in SDS2000X HD)
And example very superior BodePlot.
4 math channels with formula editor. Math channels can cascade.
(Filter, +, -, x, ÷, ∫dt, d/dt, √, Identity, Negation, |x|, Sign, ex, 10x, ln, lg,
Interpolation, Max hold, Min hold, ERES, Average, Formula Editor
2M FFT)
Always in normal mode background working acquisition history buffer.
Also (optional) comprehensive Power Analysis.
200MHz BW SDS824X HD
2GSa/s for 1 channel // 100M memory
1GSa/s for 2 channels // 2 x 50M
500MSa/s for 3 and 4 channel // 3 or 4 x 25M
Full resolution 500uV/div (Rigol have 1mV/div full resolution)
Always available true dots mode. Displayed interpolation is post processed so also after stop it can switch for display true sample dots or change displayed interpolation for x or Sinc (including also history buffer independent if it is captured in normal mode or fast sequence mode.).
Naturally also math channels can cascade.
