Nor would he say if the resignation letter has handed over at the beginning or end of the meeting.
"We have accepted that resignation. That safeguards his coaching future. We accept that 2013 wasn't a successful year in terms of the performances," said Cobb.
"We've learnt a lot ourselves and we're not afraid to accept some of that responsibility. Clearly [we need] to bring that faith back into the rugby community and the community in general."
Karl Hoskin said yesterday morning he had nothing to add to the union's press release and did not wish to comment further on his departure only halfway through his two-year contract.
Previously, he had stated he was keen to stay so long as the board continued to back him.
However, after such a disappointing season it appears that is simply not the case and a successor may have already been approached.
The Wanganui coach also serves as a team selector.
"The WRFU is expected to make an announcement after the weekend on the appointment of Wanganui selector(s) for next season," the press release said.
Cobb would only say yesterday the WRFU has three options "appoint, negotiate, or advertise", which he listed in that order.
Names which could have been approached include former coach Jason Caskey, bitterly disappointed not to be reappointed last season, his deputy Jason Hamlin, or 2009-2010 coach Guy Lennox.
Reactions of Wanganui club presidents spoken to yesterday ranged from surprised to acceptance of Hoskin's decision.
Pirates' Nga Apai felt winning the Lochore Cup may have saved Hoskin, while he respected the vision of trying to strengthen the team's future by blooding 16 new caps this season.
"I'm probably the only one in Wanganui that will back Karl.
"I could see where he was coming from no offence to the older players, but their time is due to come to an end."
However, Apai added, "Karl had the players, he just didn't use them like Caskey or Lennox."
Ruapehu's Bruce Cranston, whose club provided the bulk of the team, felt the players also needed some accountability for a lacklustre year, while the wider problem of losing promising youth as a feeder union to ITM Cup-playing neighbours also had to be addressed.
"It's a shock to me given there was a two year contract offered," he said.
"I feel for Karl, but people demand excellence.
"It's based on performance, isn't it? And the WRFU expects results."
Border's Kevin Murphy was not at all surprised.
"His results weren't that great. I think he had no choice, really.
"Just some of the comments the captain Peter Rowe made in the paper, there was no team spirit there.
"There was something wrong.
"If the union is consistent and sacks Jason [Caskey], you have to have a pretty good performance to stay there."
From Hoskin's own club, Marist's Richard Metekingi was worried about the future if the Wanganui coach always felt like he was on the chopping block.
"In a way, I thought young Caskey shouldn't have got shafted last year.
"As a club, we still support Karl and wish him well.
"Maybe there was some pressure on him [to quit], I would rather they stay there.
"I think most coaches, when they take a job, they look at a three year plan, but here they get two."
After seven straight years of making the Meads Cup final, Wanganui was eliminated in the second-tier Lochore Cup semifinal by Buller, 40-30 at Cooks Gardens, finishing seventh overall in the 12-team competition.
It meant finishing 21st out of 26 New Zealand unions, with only the 2002 team doing worse fifth in the old NPC Division 3 to be overall 23rd in the 28 years of the national championships.
Hoskin joins Bruce Polson (1992), Peter Kemp (1991) and Ken George (1995) to only serve one-year terms coaching Wanganui.
