Went to DL today before work(I run a swing shift, 2:30 - 11:00), amazing day, 75°, no crowd(hit Space, Indiana, Pirates, Buzz, Monorail, Trolley plus won a Dreams Fastpass for myself and my daughter, but no line meant I didn't use it).
As I was leaving through DTD to my car(3 hour parking but if you buy a sandwich from La Brea Bakery you get 2 more hours) I stopped by the
DVC booth where 3 CM's were hanging out.
I asked "Has Disney announced the new Grand Californian DVC's yet". One CM said "this week", another said "Friday", and the last one said "We don't know anything about this" wink wink.
I'd say we hear about it by Friday.
