With the surprise cancellation of the Legion of Super Heroes animated series, the spin-off animated comic, Legion of Super Heroes In The 31st Century is likely to be the next title on the chopping block. The comic is likely to ship its last issue by fall 2008.
As for The Batman Strikes!, that title may survive a bit longer since DC Comics wants to keep an all-ages Batman title on comic shelves. However, with the upcoming Batman: The Brave And The Bold (tentative title) animated series, that title may be shelved to make way for a new comic based on the upcoming animated series.
Stay tuned for further confirmation and updates.
