Rather like saying "we're IAG, we have experience and we reckon over the next A years short/long-haul travel will grow B% p.a. so you, Comac, should be looking at producing X airframes per year carrying Y passengers over Z miles."

"We also think C% of travel will be premium so you should look at outfitting for that much of the market".

Whether that will translate into orders (if you build it, they will come) is a whole other question.
