Looks like the Player Profile is now a variable length according to the SEQ guys. It appears to have changed at some point between September and Oct 24th. Here are some diffs that show what they did to resolve for reference.

And here are the actual structs and packet building they use currently:

Also, here are the opcodes they use currently:

World Opcodes

Hopefully this will be a good reference for getting at least the Player Profile working as well as assigning many of the needed opcodes.
