Only Apple can say for sure but I would say they will be producing the iPad 2 till at least the end of the year and most likely even longer. It seems like they are following the pattern of the iphone 4 and 4s. They continue to make the iPhone 4 as a lower cost device and I think the iPad 2 will continue as well. As it stands now the iPad 2 is still one of the most capable tablets on the market. Also, with lots of android tablets hitting the market at lower costs it will be a huge selling point to also have an iPad in a similar cost category.
