How accurate is Wikipedia.... as If you look on the BB uk wiki page its added BB 19 info on to its chart list and it states it will start in July sometime....
Personally I'm hopping for a June 13th Launch... But I know someone who has there first round BB Audition on the 12th of May... If they were hopping for a mid June launch, its unlikely that they would still be on the first round of the addition process.
