Other things to consider:
The last 4 WWDC's have taken place in Moscone West.
The last 3 WWDC's have taken place the 2nd week of June.
According to the Mocone Center's website, June 7th - 11th is apparently free in Moscone West.
(See attached image, or their event listing on their website)
That week is free along with:
June 21st - 25th
June 28th - July 2nd

It seems he may be trying to hint at an earlier date for the WWDC. I know he's not an insider, but apparently he's usually correct about many things Apple.Engadget also reports a possible introduction event date of June 22. Last year Apple announced the 3GS at the WWDC keynote in early June. If WWDC is held the week of, say, June 7, I wouldn’t bet against an announcement then.
