RSE Pokemon were definitely going to happen (in post-game and unlockable content), seeing as how certain RSE pokemon weren't catchable in DPP. (This is not counting the GBA slot exclusive Pokemon.)
Reminds me of how FR/LG actually has the GSC legendaries (But I believe they were event Pokemon too :/)
EDIT: Is there a way to obtain Mew yourself in DPP? (This is not counting online and GBA slots) If not, don't be surprised to see Mew in HG/SS. Unless Pokemon Ranch took care of that.
Celebi without a doubt will be in HG/SS considering it's a GSC legendary.
