Thank you for those great pictures!
Indeed it seems that the left hand side (where old Aspire was) will remain separate from the oneworld lounge on the right (where BA used to be).
I’m not sure if this is good or bad news. While a separate “oneworld-access-rules-only” lounge might be nice, I am now a bit concerned about the use of the (very limited) space up there. A combined lounge could have used that space better imho.
