This company (Memphis Meats) estimates they'll be in stores in four years. Other companies are working on this too. It may take awhile to perfect but in the long run it's going to be so much better. I wish I was younger because so much great stuff is coming and I want to see it all. Don't be afraid of change when it's good change.
