First time doing this, but I wanted to know if anyone else other than Ysgarran has it/has seen it. (nothing personal, just want second source confirmation).
Masters of the Wild's official street date is Friday, February 15.
Wizards of the Coast seems to actually be taking the street date seriously for a change -- they've been rather lax about this in the past, resulting in a great deal of hobby retailer anger being directed at them -- so in many cases the books won't be arriving at retailers until the 15th. Your favorite stores should all have it on the shelves by Friday afternoon, though.
Barring a disaster with UPS, we'll be shipping MotW to our mail order customers first thing Friday morning, and the books will be on our shelves and ready to sell when we open. We're getting plenty of copies and are always happy to put things aside for people, so give us a holler if you want one.
