Will new iPad with new dock connector be released by March 2012 at the earliest?

According to reliable Asian source, Apple seems to release new iPad in 2012 March at the earliest schedule.

Source said that, new iPad has same sized LCD with iPad 2, however it’s not clear if LCD is Retina display or current one.

One of the reason of this unusual rush schedule may be related on 2 weeks earlier Chinese New Year ( 23rd January) and national holidays(22nd to 28th). In next year, Chinese factory can start to assemble iPad since January end.

New iPad seems to have re-designed dock connector. Dock’s 30-pins and electricity specification will not be changed, but shape will be more smaller than current “iPad dock connector”, which has released April 2003. New Dock connector design will bring compatibility problem with current dock connecting products.

Another source told, new iPad has black and white case color models, and “One More Thing” of iOS device is prepared. This another iOS device and color information is not reliable, but it’s interesting.
