In  view of booming sales of the Nexus 7, 7-inch Android tablets are  expected to take up at least 70% of the total sales volume of non-iPad  tablets, with the remaining 30% to be for 10-inch Android and Windows  8/RT models, according to sources from Taiwan-based supply chain makers.
The  sources pointed out that the 10-inch Android tablets may see a  significant drop in demand as they will be sandwiched by Windows 8/RT  tablets and 7-inch Android tablets. Many players are already cutting  10-inch Android tablet projects and turning to develop Windows 8-based  models.
As for the tablet market in China, excluding Apple's iPad  which enjoys a high popularity in the region, players such as Lenovo,  Samsung Electronics and Asustek are all having difficulty competing  against the local white-box players due to their rather competitive  pricing; however, the first-tier brand vendors still plan to launch  7-inch tablet models with prices around CNY1,000 (US$160) to compete for  the market. Asustek reportedly may launch a 7-inch model with a high  performance/price ratio in the first quarter of 2013, while push its  shipments to achieve its goal of shipping 10 million Android tablets in  2013.
