It's just my choice of words, I don't think they are calling it that. I doubt they're gonna focus on monetizing it any more than the library manager they already have (which is to say, not at all). You can probably buy commercial IP cores for the FPGA they are using, but I seriously doubt they will be distributing those through Arduino. I fully expect that it'll be open source modules developed for functionality appealing to makers, the Arduino people have a history of being good citizens (excepting the weird copyright controversy, but that's not the same thing). Stuff like e.g. RGB LED matrix drivers, audio DSP or computer vision that fit hobbyist projects, but which microcontrollers struggle with.
