I don't read the twitter so I didn't know that most of the back setting of DxD had been revealed, but the stuff with the Four Gods (I will call them Shijin from now on) was revealed in relation to the Slashdog web novel according to what I read on his blog. They appear on the third info page (that also contains the info on Evil Dragons, Vampires and Magicians) as the Sacred Beast who govern the "Five Great Head Clans" who are {?} hunters (not sure how best to translate 異形 to fit with hunter). Among these five families are Akeno's Himejima clan, who are governed by Suzaku, and the Shinra clan, who are governed by Byakko. The others are the Kushihashi - Seiryuu, the Doumon - Genbu, and the Nakiri - Kouryuu. For more information see: http://ishibumi.exblog.jp/i32/.

As for the Malebranche, that info probably appeared a month or so ago (based on how long you'd not checked his twitter B214). It shows up on the 1st info page at the end of the Devils' section, but only as the group name and a short description, no names. They come from Dante's The Divine Comedy - Inferno, and there are twelve. (Try checking wikipedia) Their names will probably be the same... And yes, I think its a given that they'll be released (by Euclid) and become powerful allies of Qlippoth and enemies of DxD.

As for Rizevim: there's no doubt that he is is powerful as he's both a Super Devil and the son of the original Lucifer, so I doubt it will just be about his Sacred Gear Canceller (though there might be more to it since his "true" form most likely has yet to be revealed). The real issue will be whether the members of DxD, namely Issei and Vali, be too powerful by the time they have a proper fight with him, thus rendering it as dissappointing. (In all honestly, I had hoped for a little more from the Old Satan Faction arc, expanding upon their families and powers and such, but they were all a big disappointment.)

As for the fifth arc, I doubt Rizevim will be a villain in it because this arc will probably continue on until his plans are completely foiled and they hold a final battle with him. If somehow he continues to be one, he'd probably turn into some relatively pathetic character, and I wouldn't want that. A villain who is no longer a real threat but doesn't know when to give up is just sad.
