Brownsfan, I think the 3.7i upgrade is straightforward, if a bit mysterious in terms of what's actually in it. I asked Wendell about more specifics, he said he doesn't yet know the details of how the upgrade program will work, but that the information will be forthcoming once he does. He also says that the 3.7i isn't a 3.8. But I gather he's confident in the sonic improvement and the reaction of reviewers and customers who hear it, to the extent that he doesn't feel he has to tout the improvement in the sound.
BTW, while I don't think Wendell actually misled you about the 20.7 -- when I spoke to him at the time, he sounded genuinely unsure about whether they'd be able to improve the 20.1 sufficiently to have a new model at the end of the year -- I don't think they'll start announcing new models early. They have to wait until their dealers have been notified before they can do that. So I think that's one question that will never elicit a meaningful answer, except maybe right before the show when the new model is about to be released and they're in the process of publicizing it.
