Well over all he had no more power but now after fighting Ulquiorra with the new form there really is no point to Grimmjaw anymore. Isshin and Ryuken are fan combatants they have not shown themselves nor seem inclined to. Therefore they aren't really important to ponder where they are. Not to mention Ryuken possess no more danger then a master qunicy who weren't a match for shinigami in general. In any case he would outclassed in the current situation and he largely has a very small role in the series besides being Ishida's father. Shinji is to date the only one who has ever injured Aizen.
