So long story short: Siglent announced they will release a new scope on December 12, which you probably know is the new 800HD series for completion from Rigol.
But today they already put the product information on JD and TaoBao, China's two biggest online stores.
And the price is astonishing to me: every different model has the same price as the Rigol DHO800 and 900 Series. So let me explain a bit.
DHO802: RMB 1,999
SDS802X HD: RMB 1,980
DHO804: RMB 2,299
SDS804X HD: RMB 2,280
...
you get the idea
And the Siglent has 2GSa, 7 digits frequency counter, faster waveform update rate, better UI... Pretty much every spces just better that Rigol
Here is the Chinese specs sheet.
