The IdeaTab S2-10 will launch in the second quarter of 2012, though Reynolds said it was too early to share price information.
The other new IdeaTab models available only in China will have 5-inch, 7-inch and 9-inch screens. The 5-inch model will have voice capabilities and display images at a 800 by 480-pixel resolution. The larger screen models will have 1280 by 800 displays and run on Qualcomm's Snapdragon processors. Reynolds said the IdeaTab S2 tablets could become available worldwide depending on market needs.
Lenovo also detailed its cloud strategy, saying it would design devices so applications can access or exchange data through private or public clouds. The company hopes to combine content, infrastructure, access devices and middleware as part of its "cloud solutions."
Much like Apple's mobile device strategy, Android tablet makers are looking to wrap together hardware, software and services. Lenovo wants to become a content and e-commerce enabler, and wants to provide a common look and feel for videos and music accessed through the web.
"We need a solid, reliable infrastructure of data centers, servers and storage running over a common backbone and connecting regional infrastructure as a services partner in order to maximize the speed and efficiency," Reynolds said.
The cloud service will be launched later in 2012, the company said.
Lenovo also said it was assigning a new IdeaTab brand name for consumer tablets.
"As we expand mobile Internet and digital home devices around the world, it's really important for us to have a common identity, including China. From now on, our consumer tablet devices will be known worldwide as IdeaTab," Reynolds said.
