Corn!
The entry by itself is unremarkable. However, combined with the fact GRRM told us he was trying to complete the book by June, leading people to expect news in early June even if it was just that the book has been delayed again, and the simultaneous removal of the 2009 release date by Bantam, leads to the inevitable conclusion that the book has been indeed delayed once more.
Not unless you are using a different definition of the word 'inevitable' than is usually the case. That's a speculation, albeit possibly a reasonable one, not an inevitable conclusion.
The original remark about aiming to finish by June was not a firm target - it didn't lead me to expect news in early June, particularly not given past history. The removal of the 2009 release date looks reasonable given the fact that the book (evidently) isn't finished yet, but this may well be unconnected.
As for it being 'delayed once more', I kind of take the view that GRRM hasn't given a specific completion date, so the 'delay' is a process not an event. Every day the book isn't finished is a 'delay', really.
ETA - I suppose what I'm saying is that you appear to be looking for straws in the wind, and I don't see the point.
