if they announced cis v4 is going to be ready in feb than cis v4 will be out in feb.
I agree. I know that there are unexpected delays, but one should try to account for these delays when when proposing a release date. In other words, if a current schedule suggests that the release will be ready in Februrary, you may want to propose a March or April release date to account for any unexpected delays. And if you have no such delays, then you release the application early (users will be happy with an early release!). Having said that...I would offer this: propose a broader time of release such as "expected to be released by summer 2010." This type of statement is much less likely to build false hopes and unrealistic expectations.
It will be ready when it will be ready, and I am willing to wait without complaints (after all, this stellar program is free). However, I wish Comodo would not shoot itself in the foot by creating potentially unrealistic expectations.
