PG have known to do multitudes of market segmentation test before introducing products.Same applies to any major brand.
Sometimes these tests take years before a formal on the shelf product launch carrying a certain technology.

The new product line will definitely be segmented geographically for one. So all in all royalties from sale of billions of products will remain a myth before it is safely assumed that there are no adverse factors. A safety endpoint with no adverse factors is carried over years.

Here is a nice paper that details how these segmentation is done before product launch. Although not PG context it lays out the basic foundation of knowing your customer. I would assume that PG studies would be much more detailed then these.

If PG get hit by lawsuits with even the slightest adverse effect , they will have to pay out more than the combined market cap of OBJ in one lawsuit only.
