This arrived in my inbox yesterday. I don't read Fantastic Four as I've eluded to earlier on this week, so I didn't really care. Then I heard this was actually a teaser for Fantastic Four #600. Next to arrive in my inbox was this second teaser...

Follow up:

Now, I'm not one to pick holes or anything but if these are Fantastic Four #600 teasers then how come the team in question still have their Future Foundation uniforms on? Let me know where I've gone wrong please, I'd like to clear this up otherwise I'm writing a strongly worded email to Marvel. That'll show 'em.
