Staples President Demos Parneros said he expects Amazon will launch five or six new Kindle devices, according to a report.
Parneros also said that among those six, he expects one of them to have a 10-inch screen to match up with Apple's iPad.
The comments from Staples' chief were reported Monday by The Telegraph, which said Parneros comments back up those of others who are saying Amazon may have several new devices ready later this year and likely in time for the holidays.
In the last couple of months, rumors have intensified that Amazon is going deeper into the hardware end of tech.
Last month, a report came out saying the Seattle company could announce and launch a Kindle Fire 2 as soon as July following Google's announcement of the 7-inch screen Nexus 7, a direct competitor to the Kindle Fire.
