It won't be 2015, if they do it effectively. This was discussed earlier by Rass, but it fairly old now.

basically though, to get past the sheer pretension that would come about with DC costumed superhero teamup, DC costume, DC costume... they need to do most of them seperate. and the choices for 7th spot:
 * Solo Superman
 * Solo New Batman
 * Solo Revamped Green Lantern
 * Solo Aquaman
 * Solo Wonder Woman
 * Solo Flash
 * solo black canary see below
 * solo green arrow Not as long as Arrow is running, unless it's made canon to Arrowverse(?)
 * Solo Hawkman
 * solo martian manhunter, Pending, are they making more of John Carter?
 * Adam strange
 * Vibe
 * Cyborg
 * solo Captain Atom
 * Solo Ted Kord, just for tupka.
 * Solo Atom
 * Probably more but they're the most realistic I can think that they'd include.

they need to copy avengers though, DC universe is too serious with guys running around in tights. Marvel's guys are often more film-friendly so ensembles like X-men still work, but Wonder Woman, Aquaman? they need to be seen in their glory alone before they can be taken seriously together.

Imagine if we had avengers without the lead up. They'd have looked like goofballs, but we saw how each of them could save the world alone. That allowed us to know to take them seriously when they teamed up.
