Jeff Bezos, CEO of Amazon, in May was interviewed by Walt Mosberg at the D6 all things digital conference.
Mosberg asks Bezos if the recent kindle price cut (from 399 to 359 dollars) is in preparation for a new kindle model. Bezos says it's not, the kindle is selling well and they are extremely happy about it. He also says that there will be a second, a third, a tenth version of the kindle but that the second version is not that near.
