The PPS should go to around $0.15. After the first year, assuming large sales volume (500,000 units), the PPS should go to around $0.50 - a nice P/E for a new field.
Stop saying it is going to a dollar. The company may be bought out for $0.75 or $0.80 a share if the product goes really well, but I doubt this ever sees $1 a share.
