Re: IDW Star Trek Ongoing...
I doubt it. Why stop? They just have no reason to announce what the next issue is this far in advance.
At the very least, issue 24 is guaranteed since IDW usually releases four issues minimum in their graphic novel compilations, and you need issue 24 to get that minimum.
