I think we will have lengthy pause before round 4. Not 100% sure about schedule but seems to me there is sort of break from top snooker after this WC. We will continue for sure if we get another Sportsbet sponsored event even if it is smaller or if that doesn't come in near future with next big tournament.
Nothing on Snooker Calendar page in May and not even in June. Not sure also what is planned in the future as there are no feedback on official sites. Hope that Im wrong about that.
