Well do not even think of the term 'delay' or 'slip in schedule'. You have beaten up enough hype to keep people on toes expecting this thing to come out.
In fact it will be very interesting if we see commit logs on something like Github. A lot of people follow a certain project(s) which they like.
That may also help you test and flush out bugs as needed while soliciting feedback.
All the best and expecting to see a solid product out!
