Smackdown teasing the returns of Stone Cold, Hogan, Steph and Foley? (spoilers)

So, is Smackdown teasin the returns of Stone Cold, Steph, Foley and Hogan? Why is Stone Cold and Foley being teased on SD when they are RAW guys? Are they being swaped to SD?

This gives me the feeling that Smackdown is teasing the return of all those superstars listed above, that's why they are playing flashbacks of them all.

I hope they all come back, I miss each one of them.
