Sadly I doubt they will make one, SC:RM didn’t get one, but I cant say for sure that this wont.
Something of note though blizzard now has a program that if you buy a Digital copy of the game, and then later get a physical collectors edition they will credit the digitals cost to your battle net account. I do this for most of their game, I buy digital to play launch, then within the next few days I go and pick up my physical.
