I think the new diamond level is something interesting for members already used to achieve Plat and more ... just motivating them to don’t “waste” any night out of Accors.

I don’t think it will move Silver/Gold customers who already join another program at different hotel chain, except due to competitors’s faults.

What i can see on my experience, would be better if Accor improve existing members’s treatment, to don’t loose them

to loose a customer is just 1 minute. To get a new Plat or Diamond customer (or to mantein an existing one) not the same ... and you can’t get it just offering some Suite upgrades
