I'd be interested to know too. I automatically assumed it was their own decision to step away, but I'm now not sure this is the case.
If it's not, it's a bad decision as Aled was a great at play by play, and I thought John was superb at summarising and at interviews.
Although I think Gareth is also a very good commenator, with the loss of those two and interviews being nearly non existent, IceTime TV has definitely taken a step backwards this year.
