Tour Schedule Question

Tim Finchem is expected to announce the parameters of the 2007 Tour schedule this week. So I'm wondering, and wondering if anyone else is wondering...

The British Open and PGA will likely be played on their current dates (although wasn't Finchem trying to get the PGA to move up or back a week?).

The season will then conclude with four mega-purse events (New York, Chicago, Boston, Tour Championship), creating a "playoff" that will theoretically prove exciting because of a huge bonus pool.

So besides theoretically asking the players to enter four straight events after a major (!?) at the hottest time of the year, won't this kill the chances of luring big names to the events between the British and PGA? And do they really expect these guys to play five weeks in a row?
