Questions for Titans Return Toyline

With Titans Return coming in 2016 I'm eager to start collecting some of the Titan Masters such as Skullcruncher and Mindwipe if it's released, however I've recently been looking at Titans Return Optimus Prime (the Ultra Magnus Retool/Repaint) as I'm mostly a collector of Decepticons i am hoping that there will be a Titans Return Nemesis Prime,
years ago i collected Car Robots Black Convoy (RiD Scourge) and i do like it very much as it does have an actual trailer with a weapons base and Black Convoy looks rather awesome but can someone tell me what the chances are of Takara doing a Black Convoy repaint? TR Optimus is a figure i like the look of however i'm willing to collect Optimus and wait for a Black Convoy figure from japan to be released or i could go ahead and collect two and repaint one.
I also missed out on getting Metroplex as i was in Scotland at the time of release on holiday and bringing back home such a large figure would have been a bit expensive...and i did not exactly have the money to spear at the time however i am wondering if it will be released, with Trypticon coming up in late 2017 i think they may release it again but I'm really not sure.
