That G66 statement ("..the countdown would be the update of my order") is open to all kinds of speculations, thus fueling the rumor mill even more, which I think is the whole intent of the quote. I just got a B-Stock Ultra (I used to own an Ultra last year, sold it, missed it, and now I'm awaiting my order with the MFC-101 as well). If it turns out that it is indeed a v2 release, then I won't be disappointed at all, just curious to see if it adds anything that I NEED.
It reminds me of digital photography forums. As a photographer/musician, I make money off of my tools. I don't need to have the latest and greatest DSLR, however, there are those that do, whether they need it or not. My philosophy is that if your current tools are good enough to satisfy your specific needs then there is no point of upgrading. However, your needs change all the time. For example, I now need to shoot video with my DSLR, so I recently HAD to upgrade to a camera that could handle both. In terms of guitar rigs, the Ultra is all I need. It doesn't cover ALL of my needs (i.e. looper deficiencies), but meets almost all.
