Where is our new game for this week? Holiday sale applies for older titles, but a new release is expected. Where is it? Why is it not here yet?

Riven was the last release of 2009

Taken straight from the first line of the news article about the release of Riven: "[...] but is also our last release this year."
So, no new release 'till 2010.
(At least, we have some time to play those games we already own. :D)

I think with this latest sale the first 6 months of the next year for me are booked solid in terms of gaming. Although somehow I doubt the folks at GOG are just going to sit quietly and let me catch up before releasing more games I need to add to my queue.

I'm glad I read the news.
