So this was the new anime that type-moon were hinting at, the source material is pretty straight forward so not a lot of chances for fuck ups though I am wondering which route they're going to go for. The servant's obviously Red Saber aka the second saber that's not garbage like arturia. This should start airing somewhere in 2017, probably spring if I had to make a guess.
There was also new news for the Heaven's Feel anime adaptation it's apparently going to be 3 feature length movies and the first one is set to come out in 2017, exciting times.
