I believe it is 3- 4 hundred dollars more to update the regular Maxi-Sys Pro than regular Maxi Sys and about 5-6 hundred more to update than the  Mini .
I think after the one year of free updates is over , budget challenged owners of Maxi Sys Pros,  should have the option to update  Pros at lower regular Maxi Sys update cost with understanding there won't be  access to OE j2534 files from Autel's Server. More people could then afford to update their Pros as a regular Maxi Sys. When the need arises for programming  they can  chance 24 hr OE subscription off their laptop with the Pro's j2534  as a generic non validated device to program with.
