Reason those trophies are bronze is that they wanted to have so many of them and they are limited in the amount they can give for a PSN title.
The way it works is the following :
1 gold = 3 silver = 6 bronze.
Eden : 19 bronze + 1 silver = 21 bronze equivallent total.
Stardust : 7 Bronze + 4 silver + 1 gold = 21 bronze equivallent.
DLC of PSN titles seem to be 6 bronze equivallent.
1st stardust DLC is 2 bronze + 2 silver = 6 bronze equivallent.
2nd stardust DLC is 1 gold = 6 bronze equivallent.
I will agree that the Eden 3p trophy is a bit retarded but as the title doesn't have a platinum trophy it's not that big of a deal..
