ElePaperAction is, sadly, based on the Read Or Die franchise (http://en.wikipedia.org/wiki/Read_Or_Die
) and the rights to the IP would be prohibitively expensive compared to what we'd expect the game to earn. Plus, it's even older than Chantelise and this has a number of rough edges; I'm not sure even EGS would be that keen on licensing it out.
Mail Angel?... well, something might happen with that. Our slate for 2012 currently looks pretty full, but you never know! Of course, we've also heard on the grapevine that another company might be releasing it, though we've yet to see any fruits of that particular labor...
And yes, what was released Territoire-wise at C81 was the "Version 2.5" demo. It features a few new characters and a lot of mechanics updates. We still don't have a solid date for TT, but I really suspect we're in the final push and that EGS will try to have it out some time this year.
As for Bloodvane, Platine Dispotif is really close to Rockin' Android, so I would suspect they already have the rights sewn up for that one.
