About Sinergy, Alexi has said all the possible answers (we'll finish it some day if we have time, it's part of the past, maybe one day, probably not, next question, not that again, I don't think we will... the list could go on for ages), then Roope when asked looks like he doesn't really know what's going on, and then I remember Henkka beeing interviewed and saying something in the lines of "I guess if they have the time and gather they could finish it", which is like saying "yes no maybe". Kim is nowhere to be found or heard, Lauri doesn't know what's going on either and same with the drummer. So the only thing left to do is wait and see. I at least think that one day Kim will get back to the music business (not necessarily with Sinergy) and we'll get at least some info.
About COBTV part III, I think it's clear it won't come from Blooddrunk and that we'll never see where the "Alexi goes Yngwie" came from, but I think (and hope) they'll do it again when recording the next album.
