Yes, the wait now seems to be very nearly over! We've been hearing internal rumblings within Ossian for a couple weeks, but I didn't want to say anything for fear of yet again being disappointed. However, I have just received an official e-mail from the Powers That Be that we are now sure enough about an impending release that we can officially announce it.
We do have a projected release date, but not one that is sure enough yet to announce. Depending on certain developments, it may slip by a few days. Given the bad feelings about the previous seemingly-interminable delays, they don't want us to mention the date until it is 100% rock-solid. But, it seems the day it is announced will also be the day you will be able to buy. So there won't be any further anticipation once we hear.
In addition to the official Bioware and Atari boards, keep an eye out on the Ossian web site in the coming days and weeks. I understand that there will be some significant updates that will include a message board specifically about Mysteries of Westgate which will almost certainly contain useful information, especially once it is actually released!
And suffice it to say, I think that will be much sooner than most will at this point believe!
