Question regarding the A35K's Y+ cabin:

Since the premium economy cabin will hold 30 seats, I'm assuming we have 4 rows of 2-4-2 (minus two seats in a row). Does this mean we might get a dedicated toilet for premium economy, which would replace where 2 of the seats would be?

I haven't travelled on the A350 yet, but I generally prefer the mini-cabin on long haul flights and the larger cabin on short haul flights.
