Amazon is reportedly preparing to release four new tablets and a smartphone.

The e-retailer is working with manufacturer Foxconn to create the smartphone, according to a report.

Last November, an analyst at Citigroup said that an Amazon smartphone was in the works.

If Amazon does launch a smartphone, it will enter a flooded market with nearly 400 million smartphones shipped in Q1 of 2012, according to IDC.

Android-based smartphones from Samsung and Apple's iPhone made up the lion's share of those shipments.

Four new Amazon Kindle Fire tablets are also set to go into production by late this year, according to an NPD DisplaySearch analyst.

Amazon may unveil a second-generation Kindle Fire in July, and NPD analyst Richard Shim says three 7-inch Kindle Fire 2 models and one 8.9-in. Kindle Fire 2 model are going into production in August.

Amazon could not be reached to comment on the tablet and smartphone reports. It has declined to comment on such reports in the past.

NPD this week said it expects that that tablet shipments will outpace laptops in 2016. Laptop shipments will go from 208 million in 2012 to 393 million by 2017, while tablet shipments will grow from 80 million in 2012 to 254 million by 2017.
