I'd honestly prefer they not go on a hunt to find the other members at this point. My assumptions about the next chapter title, 'A Message of Flame', lead me to believe Natsu probably summons the missing members to the GMG to reunite. Then again, it could just refer to Natsu talking to Lucy, but I hope not.
I'm much more interested in seeing what's become of the other characters, so hopefully they don't dwell too long on the whole being separated thing else its going to be a long wait every week.
