Firstly, sorry about the very late reply!
I last heard it will be premiering in July this year. It is rumored Toonami will try to air it in the US and a Japanese streaming site, Niconico, will have it online with different subs. Also heard the new one is supposed to be more directly related to the manga and not a remake of the original tv series.
Sadly, there hasn't been much officially released about the new anime. The only solid confirmation on anything is that the premier is in July.
