Ofc they can lose next gen.
Americans don't show blind alligence to any company in terms of video games. Nintendo, Sony, Sega and now Microsoft have all lead the market at one time or another(key word time not generation). Its hard to compare microsoft's xbox live with apple's itunes. While the vast majority of people will at least occasionally listen to their music years after they buy it, few people actually go back and play their old games so potentially losing some xbox live titles isn't really a motivating factor.(yes i know many of you play your old games, but the average gamer doesn't often go to a video game sales website)
Next gen's victor will completely depend on who makes the most compelling hardware at a reasonable price with the right exclusive games.
