I´m not sure there´s someone to replace him at the moment.One of the main complaints I hear about him is how he has apparently made the company way too insular, living in a complete bubble and far too Japanese centric.It´s not all bad they don´t follow the 'Industry', it´s very good sometimes, but it seems they take that almost to the extreme.
If there was someone to replace him, I guess I´d say 'nay', but as far as I know, there isn´t.
