HMV.com has an interview with Isaac Brock coming out tomorrow, and as a teaser they've posted two quotes from the article.
Regarding the band's future plans he said "I'm pretty far along with the next one as it is. I went in to making this one with two records in mind." As to when it will be available, he added "It'll be released as quickly as it's legally allowed to be. It's a partner to this one."
For those of you that haven't been following the boards, as of late last week Strangers to Ourselves has been finding its ways into the hands of international customers, and apparently even being made available for sale in Austria, so scans of the artwork making their way online. Something that was noticed is that the artwork makes reference to the album being "The Golden Casket Vol. I," meaning volume II could be what Isaac is referencing. Also taking in to account that he and Jeremiah mentioned in their Relix interview last week that 35-37 songs came out of these sessions.
