You've taken Larry's comment totally out of context, I don't think he means there will be a compiler product two or three years from now. He is just saying there are somethings that need to be done in an year or two to make Perl 6 productized in the future
Secondly for a minute I cannot imagine any serious person using a non backwards compatible language in production settings. I would seriously doubt credibility of such a business. I think you are referring to IRC bots and Rosetta code wiki submitters, which in case their use cases hardly count for production settings.
Rakudo doesn't have serious users. Nor people who wish to learn it to do useful stuff. That is why backwards compatible release is so important, to bring that seriousness back.
