It indeed past due for another anime season for Index. Given there is plenty of material from the written works to do a good solid season. Although more like them to keep spreading it out, like they have done with Railgun's anime. Half an adaptation, half filler... which I've noticed makes fans of Toaru grumpy.

Yet having Mikoto toping the charts for so long, that might push more Railgun production over Index. But at this point I just want more And given the hints in both series, they might have plans to do more with say GROUP and Misaka Mikoto.[http://toarumajutsunoindex.wikia.com/wiki/Misaka_Mikoto ]
