I personally have the same impression. The string-as-unicode implementation is 
a real advantage, moreover I also like many of the syntactic changes. What I 
would like to see, however, is a native implementation of interfaces, which 
seems not really to be the case.

Moreover, as you stated above, Python 3 will still use the GIL, which is a 
shame, as it's still a "uni-processor language". This should be the #1 
problem to be addressed, as multi-processor systems are now coming up so 
fast, however, it seems this is postponed to Python 4000. :-(

That's the real problem I see, as in ~ 4 years 8-core systems may be standard 
and Python 2/3 will only be capable of using 1/8 of the processing power.
