Although it's hard to say at this point in time, does it seem reasonable to say that Wittgenstein will be remembered and revered the same way that Hume, Kant, Descartes and other prominent philosophers are?
I'm not ready to study Wittgenstein, so I don't have any direct knowledge of him. However, I did recently hear a few people comment on him. One of the comments came from an interview on the ABC radio show 'The Philosophers Zone'. The interviewee is writing a history of philosophy book and commented that Wittgenstein is probably one of the greatest philosophers that ever lived, and he didn't realize this until he sat down to write his commentaries on him.
From what I understand, he is extremely puzzling. Not to mention that he developed two radically different philosophies. One of which a school of philosophy was built on, the logical positivists.
Like you said, it is probably to early to tell, but it sound like he has boldly left his mark.
For those who care, the website to the Philosopher's Zone is:
