At least users of wide builds will see a decrease in memory use:
Everyone saves because everyone uses large parts of the stdlib. When 3.3 start up in a Windows console, there are 56 modules in sys.modules. With Idle, there are over 130. All the identifiers, all the global, local, and attribute names are present as ascii-only strings. Now multiply that by some reasonable average, keeping in mind that __builtins__ alone has 148 names.
Former narrow build users gain less space but also gain the elimination of buggy behavior.
