Among the most rumored products are an Apple-powered HDTV, a smartwatch with fitness focus, or a full fitness band. Cook did not mention any specific products or leave any hints as to a time frame.
Additionally, mobile payments have been oft-rumored as an industry that Apple could take over, due to having hundreds of millions of customers signed into iTunes with a credit card attached. Cook said the Touch ID fingerprint scanner could be integrated into a mobile payments platform but that the whole industry is "an area where nobody has figured it out yet. I realize that there are some companies playing in it, but you still have a wallet in your back pocket and I do too which probably means it hasn't been figured out just yet."
