World Cup winning Springbok Joel Stransky urged Sanzaar to release their new Super Rugby plan soon and believes the Cheetahs and Kings should be dropped from the tournament.
The competition has come under massive scrutiny after plummeting viewership and the organisers have responded with several teams in the frame to be dropped, with the Southern Kings, Cheetahs, Melbourne Rebels, Western Force and even the Brumbies all being threatened with the guillotine.
Stransky called for the board to announce their plans so that franchises can learn their fate.
"I think they need to make that announcement and be up front and say 'that's how it is, here are the reasons, like it or lump it'," he told New Zealand's Radio Sport.
"To be frank, it's the only way."
Speculation and whispers have formed the hypothesis that South Africa will lose two franchises while Australia would lose one.
The former fly-half and now Supersport commentator believes that the Kings and the Cheetahs should be booted from the tournament.
"Financially they (Southern Kings and Cheetahs) are not sustainable. They have very low supporter bases during Super Rugby," he said.
"They're in the middle of the country, they churn out great young talents but they are not places that can economically sustain a team."
Stransky explained that four strong sides would be far better for South African rugby.
"We need a smaller pool of professional players that we can pay more," he said.
"We need four Super Rugby teams that are strong, willing and highly competitive, so we can breed a winning culture and that can go right the way up, hopefully, to Springbok level."
