There are an infinite number of numbers between 0 and 1, and yet there is no repetition. Pi and other irrational numbers are infinite yet non-repeating. I wish I knew the name for this kind of thing because I'm sure it's been discussed in philosophy (a kind of opposite, eternal recurrence, has been discussed a lot).
I don't think anyone knows enough about the universe to say whether or not there is infinite variety in macroscopic stuff, so I don't think anything can be ruled out.
