I was just talking with a friend last night about this and predicted they would re-release them down the road. Seems like they will become "seasonal" mainstays or some such deal. Perhaps they will cycle through each one, SNES this year into next Spring/Summer, and the NES for Next Summer into 2019. They could follow it up with an N64 mini and have all of them on a 3-year cycle. This would allow them to balance production, maintain a form of demand, and suppress the scalping market.
If I see it on shelves, digital or physical, then I'll snag it, but I don't plan to be waiting in ridiculous lines.
