Very curious about this. There are only ever so many hours to be worked, and priority decisions to be made - and every decision to do something is a decision to not do something else.
I only comment due to my continuing and increasing frustration at the BBA plane sprites still being utterly broken and not resolved, even at least a resolve just for the majors, 4 months after release... Considering these are at the heart of the plane designer... Seems very much like a 'too hard, takes too long, dont want to, lets move on and hope players forget, instead look at this shiny new thing over here' mentality.
