A joke comes to my mind about this question:
- Can you swim?
- No.
- And what if I pay you?
I mean it is impossible to give an ETA on something which we did not even start developing. We will only see the required time at least approximately when we will start doing the development, but then we still might encounter into issues which who knows how much time will take to fix etc. etc.
So, I don't think that it would be a good idea to promise an ETA yet.
