I would really like to see some things for the Sorcerer. With less known spells than normal add to that fact Wizard only Enhancements to add spell points, Extra feats, spell like abilities, Items that give spell points per day or use, and rest shrines in abundance their extra spell points don't actually mean a whole lot in the end. It also means there is very little variety in pure Sorcerers. It is good as a cross class because of the extra points, but compared to all of the wizard stuff they are getting left behind as a pure class.
How about a little Prestige Enhancement love for the Sorcerers? Dragon Disciple, Blood Magus, Elemental Savant, Acolyte of the Skin, etc. Something would be nice. I don't know Eberron well, but I do know they had some setting specific Prestige Classes and surely one of them might be appropriate for a Sorcerer.
