There is no news at all about Slashdog Volume 3, let alone a release date. We'll probably have to wait until Shin HSDxD Volume 2 is announced at the very least, and there's no guarantee. Chapter 3 of HsDxD Zero has already been released since yesterday. Keep an eye on AnimeSuki for spoilers to appear. I did see some new stuff on the Jap wikipedia, including Vali's dad's name and the name of the Leviathan trait. Also, it seems there was definitely fighting in the chapter.
