Wizard has released an unscripted preview of Captain America #30 by Ed Brubaker, Steve Epting, and Mike Perkins.
This issue promises more surprises in the Captain America Mythos, but I'd be hard pressed to guess what could be much of a surprise since the death of Steve Rogers.
Here's some guesses:
Someone's a Skrull.
Someone is betrayed.
Someone comes back to life.
If any of these predictions come true, it should be interpreted as absolute proof of my precognitive abilities. If not, just assume it was an off day.
