Well i guess it will depend whether they are now boarding by deck rather than cabin class as the original poster suggested, so we will need to see what times Grills passengers are getting.

I emailed Cunard about this and they replied in detail. Diamond/Platinum members will still get a priority check-in lane in the terminal, but you will be expected to turn up at your given boarding time and will not get a priority or early slot. If you do, you may be required to wait, and if that's after the restaurants have closed for lunch, tough. They didn't say whether Grills passengers would still be boarded first.
