I think it won't happen as the article describes.
TI "spin off" the OMAP and make the Sitara and the DaVinci families ("almost" same features as OMAP) that are used by several "non-mobile" applications. Many people depend on those and I am sure that they need to keep producing and developing for many more years.
Also, OMAP is a SoC that has TI proprietary devices used by other markets, like for example the DSP, and I am sure they are not selling those either.
I think the best deal for Amazon would be to make a partnership and design an exclusive "custom" OMAP (please rename) for their needs and don't sell
