@Riot. Is the next champion going to be a tank or a utility support?

I want to know so I can save some IP to buy on release or not. Last 10 champions have been 2 top laners. one was a bruiser one was a juggernaut 3 mages 2 adc (one is a jungle adc but and adc nevertheless) 1 tank support 1 utility/poke support 1 bruiser/tank jungler
