One mod has burnt his tongue last year when promising a time range for PB - see parallel, bumped thread. The company proved him wrong then, so there will be no more advance statements.
Furthermore, they have kept many trivial things as secret business secrets, a behaviour which eventually made us call them the Hold-Your-Tongue Tribe of Bay Area.
In the light of this, I wonder why that fabulous "Nation" tournament has been announced three weeks in advance - either someone will be burning his tongue again, or they need to rise a "Nation" hype to secure their revenue. Who knows...?
Some may speculate about a link between these two items - I won't. PB strokeplay is non-existant to me until I'll be standing on the first tee!
