The rumors about the next-generation iPad are coming quickly. According to DigiTimes, sources within the supply chain for the company have started to ship out parts and components for Apple’s new tablet and they have claimed that the Apple’s iPad 3 will be here around March or April.

The publication’s supply chain sources indicate that the next generation iPad parts are starting to ramp up while the iPad 2 production is starting to decline. OEM production of iPad 2 will remain high at 14-15 million units in the fourth quarter of 2011 but decline to 4-5 million units in the first quarter of 2012, paving the way for the launch of the new iPads, the sources noted.

Apple’s longtime partner Foxconn Electronics is said to be producing the iPad 3, with production starting in January and ramping up in February.

Stay tuned.
