Three additional details: four channel only, smaller memory (14Mpts/channel) and slower update rate (60kwfm/s).
. I would find it hard they would save some money by simply removing the ADC channel interleaving of the MXT201's.
I can't see in the photo what the exact part number is (would there exist an original better quality version of the photo that shows the part number on the Virtex?) but the cheapest Virtex 5 from Digikey is $250 for one piece:

Who is the target market?
Or dumping DS4000 end of life supplies?

I imagine they redesigned the product with a smaller framebuffer (about 1/2 of the original wfm/s) which may also require a smaller FPGA.
Thank you for the closeup picture of the FPGA. Looks like they are using the larger FFG676 package with more IO.
So it would be this one for $287.50 each

If the DS4000 uses 5 pieces of these FPGAs that would be $1437.50 just for the FPGAs at the Digikey price. I imagine it should be possible to design a more cost optimized version these days.
Also if they are creating a cost optimized version that is intended to sell at lower price then unless they are planning to completely discontinue the current DS4000 they will probably need some way to differentiate from the regular DS4000. For that they may limit some of the capabilities even if there would be no real technical reason for that.
Hi All - Just to let you all know Rigol have indeed released two new DS-4000E models.
These are released to fill a cost gap in the range between the DS-1000Z and existing DS-4000 for a 4 channel 100/200Mhz DSO. There are 2 models , DS-2014E 100Mhz 4 ch and DS-4024E 200Mhz 4 ch
Primary differences as has been pointed out are ;
Lower price - the above link has our local $ Aud pricing
Max sample rate 2GS/s vs 4GS/s
Memory depth 14Mpts vs 140Mpts
wfms/s 60,000 vs 110,000 wfms/s
If you follow the link as above to the Emona web site you can click on more info and download a 10 page brochure.
If you have any questions on these at all let me know.
And it's not correct with regards to the DS4000 either.
For single channel it's 4Gs/s and 140Mpts, for dual channel it's half (2Gs/s and 70Mpts). If you have a four channel scope then you have two dual channel scopes connected to one screen.
So, on a four channel version you can have 2 channels (1/3 or 2/4 at 4Gs/s and 140Mpts each) or 3 or 4 channels at 2Gs/s and 70Mpts each.
I don't read Chinese but I'm pretty sure that 1Gs/s you see splashed in there with all the Chinese tokens is reffering to the sample rate for the digital channels - which on theDSMSO4000 is 1GHz.
Hi - I'll check with Rigol and wether or not there are independent ADC's per ch. or shared and let you know.
I don't yet have a unit in country to try on , our demo stock are on order but still a few weeks off.
It's actually weird that Rigol has introduced these new models as part of the DS4000 series, and not as part of the DS2000 series.
Before, the sample rate always defined the number in the DS series:
1 GS/s => DS1000 series
2 GS/s => DS2000 series
4 GS/s => DS4000 series
They could have used the following alternatives: DS2104A, DS2204A. Would be more logical to me!
, it's reasonably priced and it's hackable...
, it's reasonably priced and it's hackable...LOL
Upgradable ? NOT easy, I think,
Could just be the DS2000 56M memory, different front end filter Amp.
