It's an open source project developed by volunteers. Understand that Magic Lantern isn't anybody's job. It may take two years or more from the time the camera's introduced. The newest dRebel model that is currently supported is the 700D (which came out in 2013) your 750D came out this year.


If you have to have these features right now, your best bet is to get a hold of one of the models that is supported. The newer your Canon camera model is, the less likely it is that there will be a Magic Lantern build for it (just as with Canon P&S cameras, the less likely it is there will be a CHDK build for it).
