“Unconfirmation” of new SE P900 Smartphone replacement

Everyone’s talking and linking everywhere … Brighthand, mobile9, Mobi-Mania, Esato are amongst some of the websites on this bit of rumor; no offence to those not mentioned.
And the rumor is Sony Ericsson is releasing the replacement to its P900 model, dubbed P910 (name unconfirmed) this coming 15 July 2004. A mobile9 forum thread has additional, larger pics which are also cautioned to be unconfirmed.
With all these “unconfirmed” bits and pieces which can hardly be called news, how did anyone come out with a launch date of 15 July? Oh, and no prices, too.
