I saw this teaser image today on Marvel.com and cannot wait! Jonathan Hickman's FF has been great these past months and nothing beats a Fantastic Four story with Galactus. I also think it's appropriate to resurrect the original title for #600 -- even only for this milestone issue.
The below image is from Fantastic Four #262 'The Trial of Reed Richards' by John Byrne. In it, Reed takes a noble stand and defends Galactus' right to exist. It remains one of my favourite comic stories and a great moment in the history of Reed Richard's character. Given Hickman's use of Bronze Age references in recent issues, there is good reason to hope we will see something like this in November.
