Red Goblin!

So if you haven't heard it looks like the first appearance of Red Goblin is going to be Amazing Spider-Man 798.
I don't know if this is just going to be a cameo or what !
I presume most of the retailers know this as well as 798 pre orders have shot up in price , try getting a copy for under a tenner on the bay!
Now the question is if he appears in 798 what's going to happen in the 800 landmark issue ?

798 is out 4th April .
