My local radio station had an interview with Greg on Tuesday (10/2) and I haven't read this spoiler yet maybe it's been mentioned and if it has I must have missed it but he says something about his power, here it is and I'm kinda quoting here:
"Mind reading is just the beginning of my powers"
heres the link to the interview (its about 1/3 of the way through)
so how else could Matt's powers increase or enhance?
if this topic has been discussed sorry it could be deleted if it has....
