The release was always going to be first quarter of 2017. So until told otherwise, assume the end of March.
They were almost ready to launch on Dec 28, but were delayed because they needed to apply fixes suggested by test group.
Applying those fixes shouldn't take more than 3 to 4 weeks, unless they're rebuilding the entire platform from scratch.
"End of March" will be completely ridiculous, because that's long enough to build an entire fund management platform from scratch.
