but what about hw differences in 2102 and 2202? (and now the DS2302a?)

No hardware differences - only software differences (which set BW parameters).

Here is something curious.
Look at the full hardware versions listed for each of these DS2072A's:
Hardware Version: 1.0.2.0.0

Hardware Version: 1.0.2.0.2
https://www.eevblog.com/forum/testgear/sniffing-the-rigol's-internal-i2c-bus/msg341494/#msg341494
Firmware and FPGA versions are the same for both though.

Yes, the hardware changes from time to time - but across the entire DS2000 line. Rigol is only manufacturing a single DS2K mainboard (or two - if they still continue to manufacture the non-A version) - then setting the model type via flash memory and front panel sticker.
neslekkim:
But both of these are the A version?, changed hw already?
Or is the hw version changing if the fpga code is changed?

I think Rigol has already stopped manufacturing the non-A versions.
Some weeks ago they already removed it from their Oscilloscope models overview here: http://www.rigol.com/prodserv/Digital%20Oscilloscopes/
And also revomed from drop-down menu at their frontpage under Products -> Oscilloscopes: http://www.rigol.com
Logistically it wouldn't make sense to manufacture and stock both models anyway, the only thing changed for the A model is 50 ohm input termination and a 300 MHz model. (But the non-A version can be hacked to 300 MHz too :-+ ).
FW vise, they have also added a CAN decoding add-on option, but this can be purchased to the non-A model too according to this http://www.tequipment.net/RigolPricelist.html so this isn't anything A-model specific.

Even though Rigol.com don't link to the non-A model page anymore, you can still find it by going to the DS2000A site and removing the A at the end of the link, like this: http://www.rigol.com/prodserv/DS2000/
Rigol have also removed DS2000 non-A from both of these 2014 PDF brochures released a month ago: http://www.rigol.com/support/prodcatalog/more.html

Electronic Measurement Instruments Catalog(2014) 2013-11-06
Electronic Measurement Instruments Selection Guide(2014) 2013-11-05
--- End code ---
The good old DS1000E/D series scopes are still in the new 2014 brochures.

alright, got a reply from rigol regarding the firmware:

@apelly Since you're prepared to do a dump i'll let you do it once you get your kit, i'm going to talk to supplier to see if they can confirm any crashing on A version that way i can rule out or replace a dud scope before opening it.
I'm also having issue with LXI, but i think thats just to do with using windows 8, USB works fine by all accounts.
