A very major threat to RSA encryption would be a solution to the Riemann hypothesis. If a solution is found, prime numbers would be too easy to find, and RSA would fall apart. Undoubtedly, much more sophisticated algorithms than RSA will continue to be developed as mathematicians discover more in the fields of number theory and cryptanalysis.
"prime numbers would be too easy to find" -- they're already really easy to find. Factoring large semiprimes is currently hard. Primality testing and finding primes for RSA keys is very easy. If the RH was proven true, it wouldn't speed that up in any practical way either.
As an experiment, assume the Riemann Hypothesis. Does that make factoring easier? No. Do we have any currently known methods of weakening RSA if the RH was true? No.
A small note to future viewers - This PDF does not mention anything about solution being a threat to the RSA encryption. It provides a mathemetical proof for something which I couldn't comprehend.
Also, on a quite unrelated note - won't any kind of encryption be obsolete of it is proved that P=NP. I read this two days ago on the Wikipedia entry of "P versus NP problem" in the "Consequences" part.
