Apparently the Palm Pre is to launch on the 6th of June according to notebooks.com; they base this assumption after seeing a Sprint advertisement featuring a countdown timer to the 6th of June, so thus believe this date is official.

Furthermore they believe the advert will probably point to the Sprint Now Network Pre landing page, and the countdown timer is identical to that of many other found on the Sprint nationwide Now Network website and advertisements.

Although there is mention of the Palm Pre actually launching today as my colleague posted earlier, to which end we are running a Palm Pre poll on whether you believe the Palm Pre will launch today or not, so nip over there and get in your vote.
