Polar Research tenders for OA publisher

Polar Research is the journal of the Norwegian Polar Institute. It’s currently published by Wiley-Blackwell. It has recently issued a tender for an open access publisher to take over the publication of this journal as reported in the Norwegian Open Access Wiki .  Is this a first? Will there be more? I came across this on the wonderful open access tracking project developed by Peter Suber. If you aren’t already signed up, I’d recommend it.
