Tom, it certainly is puzzling, why they would continue to prepare for an IPO, as well as (presumably) carry on with the day-to-day, but without the marketing that is vital if an IPO is to succeed. Yet they must feel that this undertaking can ultimately pay off, otherwise why the continued activity. Perhaps they are waiting on promising trial results, and only then would they proceed in earnest? Us shareholders, as always, are left in the dark. Nothing new there!
