Given the age of the 777 planes still on 2-2-2 (all 10+ years, in fact A7-BAA is already 16 years old and QR doesn't seem like an airline which will use 20+ years old plane), I suspect they might be removed from service in another few years when they have received more new planes instead of being retrofitted with Qsuite. Even the non-Qsuite A359 aren't getting retrofitted yet, perhaps they will get the new Qsuite when it's revealed and when the cabin is due for refurbishment?
