今日长难句：

The big questions are which, if any, of the large traditional retailers will still be on the scene in a decade or two because they have successfully reinvented themselves, which new players will operate busy stores on Main Streets and maybe even in shopping malls, and how the shopping and buying experience will have changed in each retail category．

最大的问题是，十年或二十年后，（若有的话）哪些大型传统零售商因成功彻底自我改造而仍然健在，哪些新的角逐者将在主街上、甚至可能在购物中心经营热闹的店铺，以及每个零售类别的购物和购买体验将发生怎样的变化。
