It's not a marketing style, it's just the real world.
IRM have repeatedly announced that they are increasing the size of subsequent runs to satisfy demand and keep people happy, but how far can you ask them to go, how many hundreds of thousands of Euro can you ask them to risk on a project?
The A Class project must be three or four years since announcement, and the market now is very different to what it was back then.
We, their customers, are constantly harassing them for info on how many units are being produced, how many have sold, how many are available, and it's unfair to then accuse them of marketing malice by simply responding to our requests.
