It's not clear just when these pigs would go on sale, or for how much. It wouldn't be surprising if they're limited to China, mind you -- many countries are jittery about importing pets in the first place, let alone ones with altered genes. As it stands, BGI will likely have to overcome cultural hurdles. Many people are still opposed to genetically modified animals in any form, and some of those that are in favor might still object to that practice with pets. You could argue that BGI is encouraging the ownership of pets that aren't really house-friendly, for instance. Whatever your stance, the commercial launch should show whether or not society is ready (or willing) to accept tailor-made companions.
