The next generation will support SPI and I2C communication interface, is it true?

Some informal official mentions a word or two, the new version of java card specification would support Extensible I/O Model. some new communication protocols. That's would be fine, maybe it indicates the next generation java card os will have more application scene or physical shape for deployment.
