On Twitter, C|Net’s Brian Tong has said that Apple’s refreshed iMacs should be hitting stores in late April or early May.  According to Tong, the updated iMacs will have Sandy Bridge CPUs and Thunderbolt ports, which is no surprise.  There won’t be any cosmetic changes however.

Though, you know what they say: If you are so sure of yourself, put it on CNET, not your Twitter feed.
