I think Olympus has a future, perhaps not 4/3 though. Many companies have lost their way temporarily in the rush to dslr. Canon/Nikon won't dominate for ever things change fast, tortoise and hare situations.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
