Moot, I recommend you not take responses or lack thereof personally on a web forum, or you'll probably end up like he-who-shall-not-be-named eventually.
Just because Scirra actively engages with the community doesn't mean they owe everyone who asks a response (generally physically impossible due to being outnumbered, or that they would just never get any actual work done!).
As for your specific question of " Will we have to wait long for it?", I would guess that he simply doesn't have an answer for that, and it would be silly of him to need to explain why he doesn't have an answer for it. There is no way of determining what your definition of a long wait is, and most likely there is no way of knowing exactly when or how long it will take get done at the moment anyway.
Anyways TLDR I find it highly unlikely that anyone at Scirra would take your posts personally, so you shouldn't take what they say or don't say personally either.
