You might be interested in Chris Skinner contributing to what Brad just said in Singapore, that Ripple is already taking over SWIFT:

This link came up in an exchange I have with TAS Group. The Ripple integration they did in their Network Gateway suite end of 2014 was based on the protocol version that Ripple had defined at that time.
They have not upgraded the implementation to the most recent RippleNet specifications, because they never got any “live” customer so far.
Despite the technical feasibility to offer banks a seamless mapping / interoperability between the two networks, what really changes is the trust model underpinning the overall correspondent banking scheme.
So I think it's best to not want more hyping from Brad & Co., but to just let them do their job without antagonizing any side.
