Tomorrow, October 23rd, Sony will be releasing the new system software update for PlayStation 3 (version 4.30). While the main feature is a complete redesign for the PlayStation Store with an improved user interface, there will also be changes to how Trophies are displayed on your PlayStation 3.
The first change is that the Trophy Collection will now reside under PlayStation Network on the XMB. Trophies earned while playing PlayStation Vita games will also be displayed here. Lastly, you'll be able to see your Trophy level and progress towards the next level while viewing your trophy collection.
In addition to the changes being made to the Trophy display, Sony will "retire services" available through the Life with PlayStation application beginning in November 2012.
