Wie Turning Pro Soon?

It's been going around for months that Michelle Wie will turn pro after her 16th birthday next month. Looks like there is more evidence now. Juli Inkster's (now former) caddie Greg Johnston, who has caddied for Wie in the past when Juli was taking a week off, is going to be taking over as full-time caddie for Wie. I don't know if Wie's turning pro was supposed to be a big secret or not, but if it was, it seems to me letting the caddie announce his intentions a month early is not a good way to keep up the suspense.
