I think not :-S . I just took delivery of a Casio this last Sunday from him. On Monday I emailed him to advise that I had received delivery. His, as usual, cordial response was nearly immediate and he included an offer to assist in helping me obtain any other Casios.
If Seiya-san is going out of business, I'd have to hear it from him before I'd give such a rumor any credibility.
Best regards and nice to see the forum back up,
