Difference Between E7 pro max and E9

Hi, I ordered an "E9W-EU" yesterday on the German Felxispot website with the 12% discount, it says it will be going into presale, so I assume its a new model, but now I looked again at the website and found that E7 pro max.

It seems to me that there is no difference between these two models, like at all.. except the price. The two listings literally use the same image file of the Table in the whiteroom. The E7 pro max is 399,99 € lowered from 549,99€ and the E9 is 549,99 €.

Could someone please shed some light into this? Is the E9 a more advanced version of the E7 pro max?
