New Dark Troops

Hi guys, I know everyone is excited for TH11 and the new dark troops and here are my thoughts on the next dark troops. I Think that 3 out of 4 of them are going to be ground troops and the other one is going to be an air troop. Since air attacks are pretty much OP already they don't need another troop. Now here is what I wanted to tell you guys. I was looking at the Dark Troop menu and I saw that there were 2 troops per TH level. For example we had Minions and Hogs for TH7, Valks and Golems for TH8, Witches and Hounds for TH9. Now there are 4 spaces left. So I think that the next 2 dark troops are only going to be for TH10+ and the last 2 for TH11 only. This does make sense since each of the TH's have 2 dark troops. So I think that the arrival of these Dark Troops are going to be when TH11 is released. I also think that TH11 is going to be released sometime this Summer. Just wanted to share this with you guys, so Have Fun and Keep Clashing!!!
