I had heard this rumor too and there is enough people talking about it that their must be something too it.
Another less credible rumor i heard was that GOOG doesnt have all the cash they say they have and they are doing some fancy pants accounting to hide this fact which is the reason for the secondary coming.
But lets say all is well in the land of accounting. If i was CEO and I knew GOOG was heading for a crash like every other internet stock has in the past, i would be printing and selling stock too at these rediculously high prices.
