I purchased one from Costco a few weeks ago (chocolate). It does indeed have nylon fabric based handle on the bottom. It is flush with the case so may be hard to see. As far as I can tell it is exactly the same as those that were discontinued by B+R (replaced by the new 2012 versions). Here is the main thread about this bag:
