It is not already in mass production, we would know that already.
But you are at least partially right, hardaware already exist, but I belive it is OS4 pruduct only.
Correct me if I'm wrong, but did Rogue said so in Amigaworld.net? I mean it is manufactured just for A OS4? I don't belive that is planned to be OS4 product at least originally? Maybe LimePPC laptop with new brand?
