Ok, I may have expressed that in a wrong way...
There was a lot of talks that OS4 would appear on the Peg1 still Genesi never signed the needed contracts, it was just talks to get people that wanted OS4 to buy a Pegasos.
Now there's talks about OS4 coming to the Peg2 but still no papers signed.
I am certain that Genesi and Hyperion would do a pressrelease the moment such a contract existed, therefore I conclude that it doesn't exist.
We have also seen comments from Ben Hermans that says it won't happen unless the Peg2 sells more than the initial 600(IIRC) there's produced, and then there's still the contracts that neds to be signed.
Don't get me wrong, I would love to see OS4 on a Peg2, 3, 4 and whatever they are called
