My first guess would be that the announcement has nothing to do with weapons grade uranium and will instead be something along the lines of they have successfully constructed their first reactor grade uranium fuel rods.
That was the basis of Iran's insistance on producing enriched uranium despite the repercussions for anyone who's forgotten.
My second guess would be that if they further enriched U-235 from fuel grade to weapons grade, they wouldn't announce it until after they had their first successful test of a fission chain reaction and possessed a suitable delivery vehicle to deploy a miniaturized fission device.
