It's the fact that there have been so many sudden releases, many of which have failed miserably, that are why I'm concerned for V4. Sudden releases never, ever do well. Look at Chika, anon and kanon, kokone, and plenty of others, mainly V3's. They just happen, and then disappear shortly after. Not a great marketing strategy, in my opinion. Here I was hoping that YAMAHA noticed the pattern and tried something a little more methodical and substantial when it came to marketing the new software, like they did with VOCALOID3.
