I think not, only because their attitude at the time was that the Electronic Battle Weapon series was "done" at a nice round 10 and they wouldn't do more. It was kind of a surprise when SIFSD was released as EBW11.

Now that they have EBW 11 and 12, they need to continue until there is a nice round 20.
If it were up to me, Don't Think, Superflash and C-H-E-M-I-C-A-L (especially the first version) would make perfect EBWs.
One can dream...
