Does Python compete with Java?

[kk]

I read this mailing list fairly often, and I am always amazed at what
I learn (even not related to Python).  I am relatively new to Python. 
I make my living developing mostly in Java.  Python was a "discovery"
I made a couple of years ago, and I love the language, but only get to
use it at home for hobbies.

With all the recent news:
- ESR tells Sun to open Java, or be relegated into obscurity by
Python, Ruby, and Perl.
- Project mono (C# compiler) is touted to be the next great thing in
Linux, and will be the dominate language. (by it's creator, of
coarse).
- This past weekend, Sun signs deal with devil (oops... Microsoft). 
Now Java "openness" seems to have taken a very large step backwards!

I'd like to know if you guys think Python really has a chance to
compete with Java, .NET, and any other commercially backed language.

The reason I ask is I think it is important to have a "popular"
well-supported Open Source language to compete with the big players. 
PHP seems to have some momentum in popularity, but I much prefer
Python as a language.  Python has much to offer over Java, VB, etc...
Maybe the best chance it has is to ride on the coat-tails of .NET
(Python.NET) and the JVM (Jython).  Interested to hear your comments.
