I think nobody can argue with honesty, yes, the community is impatient but a statement like this and everyone is happy .
I am thankful you want to release a perfectly polished product but as you said, work will continue after release anyway.
Let's face it, if you release with some bugs and explanations about the work still in progress, I dont think it could be a problem for you (if people are aware before purchasing) and the strong supporters we are will be pleased anyway. It's better to wait with an unpolished product than with nothing
On the other hand, trolls will be criticizing even with a perfect product...
Keep up!
