I wouldn't say we've been completely silent.
This news item from a few days ago announcing the demos talks about the release dates for both N. America and Europe (albeit in general terms).
The thing about adventure games is that their release dates are notoriously awful. They slip from original projections and they rarely give a specific day (with the exception of Telltale which makes those dates the vast majority of the time). Unless there is some concrete info, it's hard to say anything specifically. Also we don't typically do news items on release dates, we just update the
release dates page.
