X-Cart, the full-featured, open-source online shopping cart software has been promising a new, next-gen version for years while X-Cart 4.x grows long in the tooth. In the meantime, some users have been jumping off the X-Cart ship as carts like CS-Cart, ECWID, Hikashop, and others provide modern shopping cart software. Is it too little too late for X-Cart? Probably too early to tell, but you can check out the beta demo here: http://next.x-cart.com
