Sounds like irrational exhuberance to me. Some people are too close to this stock. 5 years from now with no sales, they will be still be saying "but wait until sales are posted".
Sure it is basic mathematics; increase revenues and the bottom line goes up. Is it not fear to question the reality of a company's ability to exist as a going concern when they have had zero sales and no communication with shareholders for 3 years. It is unreasonable NOT to do so.
