@Riot Any news on Karthus?

Just thought I'd check with the Riot team on if there's anything in the works for Karthus in the immediate future. I'd also like to note that I don't think he's necessarily too weak at this point in time, (the minion aggro change seems to have helped him just a little) I feel that the Ult buff given to him wasn't the right direction to help him, and with the loss of Magic Pen runes (despite the loss of MR runes as well), he's lost a sizeable bit of power for his early game. This makes his only strategy to play really passive and farm until he gets his spike, which in turn makes him feel more like a Suicide Ult-bot.

I'm just asking if he's still on Riot's Radar and if/when we can expect anything for him is all
