Well when the acting CEO publicly backs a statement made you generally think... ok, maybe it will be happening.
That's what he said, that XP OEM production and distribution to MFG's will cease as of June 08.
But as you go on to say, Newegg and other retailers/distributors will continue to sell them until stocks run out.... as for when that happens, well I suppose is comes down to how many are still out there in the wild.
