Here is a better list of upcoming series for the Fall. This is most likely not a complete list but nothing on here is fake. http://countdown.mandragon.info/upcoming.html
(also check the confirmed tab for a few more of the series)
To Love Ru Darkness it is going to first be an OVA and then after that there will be a TV season so don't expect that anytime soon.
As for Seitokai no Ichizon I have more sad news, while there is going to be a second season it also is not happening this fall and most likely won't be the winter either. I am willing to bet that whoever made that poster was either just a troll or got it mixed up with Ebiten since they have a similar uniform and some similar characters.
