No. <type 'str'> will remain a byte string type for any foreseeable
future. The only change that is likely to happen is this: To denote
bytes > 128 in source code, you will need to use escape codes. 

A change that might happen in the future is this: A string literal
does not create an instance of <type 'str'>, but an instance of <type
'unicode'>. However, IMO, this should only happen after a syntax for
byte string literals has been introduced.

The byte string type is not going away. It is a useful type, e.g. when
reading or writing to or from a byte stream.
