I received a rumor that Nikon D4 will be the first DSLR to offer Light Peak connection (high speed optical cable interface offering 10 Gbit/s). The new MacBook Pro models that will be announced tomorrow are expected to have this technology (Apple calls it Thunderbolt).
I received this rumor few weeks ago and decided to post it today after I learned that the first computers with Light Peak are just around the corner. Intel is expecting Light Peak peripherals to become available in 2011:
"Light Peak components are expected to begin to become available to customers in late 2010, and Intel expects to see Light Peak in PCs and peripherals in 2011."
Update: the official name of this new interface is now "Thunderbolt".
