Interface - 90% (not including testing. The base sticks will also work fine with the current GP-Wiz49 interfaces
I already bought two GP-Wiz 49 max interfaces so, is there going to be a new interface that will work with these ? or am I going to need to buy all new interfaces in order to use all the new options ?
The main board will be the same, but the firmware will be different. That means a chip swap is all that will be needed if you have the MAX version. The chip upgrade will be available at a reasonable cost. There will be no upgrade path for Eco's, but you won't necessarily need the upgrade. It depends on your setup.
The functionality will be similar to what has been provided by third parties in the past, but it has been improved, with additional features added, and will be wrapped together as a package.
