I don't think the topic bothers him. He, like everyone else, wants to hear about general release, especially as we are just 3 days from the end of Spring. Now, make no mistake, I love the idea of a mouse from WT, but I'm much more interested in general release of the TB, even though I have it already. So, for those who don't have it, it just makes sense that their interest would be skewed much more towards release over a potential new product. And when they get the TB, then they'll probably be more into what might come next in hopes you can make a similar quantum leap in that area too.
Heck, once they get a TB as part of general release, I suspect that if a new mouse had similar delays, those frustrated now would probably be less so - taking a view of "Well, here we go again, but it worked out fine last time and it was a great product".
But none of this happens until we get the TB general release. I do worry (but expect) that we are going to see another delay till Summer though. Not based on anything other than a lack of anything to base any feelings on! So also looking every day for other update info.
