Some may not be aware of this, but Oreimo S2 will not be done by same studio as S1. S1 was made by AIC and lisensed in U.S by Aniplex
Aniplex got the money bug bite them and realization of profitability.
Aniplex will thus be funding, producing, and lisensing Oreimo S2 (A-1 Pictures is the official studio, but they are a wholy owned subsidiary of Aniplex which is a subsidiary of Sony Entertainment Japan)
Well, I just hope that they won't ruin the character designs.
