As one of the persons involved in the litigation (I filed an amicus in the Ninth on behalf of dreamers and my law firm is probably going to be involved at the SCOTUS level if it grants cert), you should be good to go on the EAD. I, myself, got an EAD through I-485 filing under CSPA more than two years ago. However, USCIS is likely to hold your I-485 in abeyance or outright reject it. The chances of getting referred to court are very low given the new USCIS NTA rules.
I was NTA-ed and ended up in removal proceedings where i simply renewed my I-485 application. IJ scheduled a green card hearing for me in two weeks, alas, the appeal to SCOTUS means we need to reschedule that. I continue to have work authorization though, so I'm not concerned. In a few short months, I'll be an attorney.
Of course none of this constitutes legal advice and you should consult with your attorney.
