iPad 2 or iPad 3?

My brother and I would like to get an iPad for our mother so that it would be easier for her to skype on her own with her grandsons in UK. Currently she has to rely on me and my notebook. However, I am not sure if we should get iPad 2 just yet... Maybe we should just wait a while more since iPad 3 is rumoured to be out in spring of 2012 and we could then compare the two.
