Removing actual server-side content like POTD or Stone Sky Sea won't affect the viability of a glamour log in the slightest. All it will do is make fewer people play the game...
Server/network issues and PS3-specific interface issues are completely different things.
But... don't you run out of space to store glamour items? That's what the proposed glamour log is designed to address. At some point, it's going to happen to everyone who collects glamours, whether or not they invest in extra retainers. It's in S-E's best interests to figure out a way to keep people buying and collecting novelty dress-up items forever.
