The catalog shows the new versions of the RS400 and the DS400, I think they are the RTS and DTS. They are in the paper catalog, but not online at Festool USA site. The main change I see is the removeable cords but I think I read somewhere that there were more changes. Does anyone have any more info?...joe
This is covered nicely in the FAQ section of the Festool USA website.

Click on the question which reads:
What are the differences between the new palm sanders: RTS400, DTS400 and ETS125; compared to the older models: RS400, DS400 and ES125?
You will get the following answer:
The improvements made to the new palm sanders, ETS125, RTS400, DTS400 are mainly internal; you may not notice any difference in how they look.
The counterweight has been reshaped to provide better balance and stability. The cooling fan housing is now made of metal and the new fan is less likely to come in contact with the housing. This lessens the tendency for the sander to hop around, and will result in fewer swirl marks.
On the ETS125, the rubber pad brake now has holes around the periphery. This prevents vacuum lock when connected to a vacuum, which allows for better pad rotation, making the sander easier to move across the work piece. This will also results in fewer swirl marks.
Some have felt that these new sanders are not as aggressive as the older models. What you are actually noticing is improved performance and less vibration due to the improvements.
Note that the RS400 and ES400 had removable cords, just like the new models.
