New Apple product rumors from reliable sources have been few and far between lately, but this weekend the generally dependable 9t05Mac reported that a new iPad model is in the works. It’s not a brand new device, but rather a new SKU in the fourth generation iPad with Retina Display lineup. 9to5Mac’s source is saying that this will be offered in both black and white, with both Wi-Fi and cellular options, and that it will join the existing models rather than replace them.
