The curves I've seen make 2020 look like the ultimate limit, for reasons
of both size and heat dissipation. Various means for circumventing the
obvious physical limits may exist though.
I would be interested to hear what people think about the possibility of
extending the reign of Moore's law beyond 2020, when we hit atomic-sized
components, dissipating kT Joules per operation, assuming it continues on
its merry path for the next 20 years.
What are the possibilities for increasing computer power beyond that point?

(Do you mean bips, not mips?)
ASCI Red at Sandia Lab has reached up around 1,830,000 megaflops.
