Sony hasn't released the new trophy level formula or officially announced the new trophy point values, so I thought I'd start a thread with this information. None of this is official -- it's all reverse-engineered by looking at people's profiles.
New trophy point values:
Bronze: 15
Silver: 30
Gold: 90
Platinum: 300
The only difference above is that platinum trophies are now worth more (300 points instead of 180). The values of bronze, silver, and gold trophies did not change.
New trophy level calculation:
Once again, the trophy level calculation is not a smooth curve, but rather has cut-offs. Here is how it works:
Levels 1 - 99: 60 points (4 bronzes) per level up
Levels 100 - 199: 90 points (6 bronzes) per level up
Levels 200 - 299: 450 points (30 bronzes) per level up
Levels 300 - 399: 900 points (60 bronzes) per level up
Levels 400 - 499: 1350 points (90 bronzes) per level up
Levels 500 - 599: 1800 points (120 bronzes) per level up
Levels 600 - 699: 2250 points (150 bronzes) per level up
Levels 700 - 799: 2700 points (180 bronzes) per level up
Levels 800 - 899: 3150 points (210 bronzes) per level up
Levels 900 - 999: 3600 points (240 bronzes) per level up
Platinuming a single game gets you to level 23 now. It takes a total of 1631340 points to reach level 999, which equals roughly 1200 full games platinumed.
