Having looked at the Cathay response on Facebook I must say that I support the group that think the flight will be launched 'later rather than sooner'.
Look at the wording of the reply "Hi Simon! Thank you for your inquiry. Please stay tuned for our official press release. Thanks" - does that not look like a very standard response which can interpreted in any way that the recipient may wish? I do not see this as being a definitive response.
