On this week's episode of Rumor Roundup, Mark L. talks about Amazon's rumored live TV service, Apple releasing a 4K 21.5-inch iMac, and there's going to be how many versions of the Galaxy S7?

Similar to Sling TV, Amazon is apparently in discussions what CBS and NBCUniversal to offer its own live TV service, though talks are preliminary right now. It's unclear if the service will be bundled in the cost of Prime; if it is, it'll be one killer deal.

Meanwhile, it sounds like Samsung is going to release three different versions of the Galaxy S7, though it mostly comes down to the type of chip being included. Europe might get the Exynos M1, India the Exynos 7422, and the Snapdragon 820 here in the U.S.

Finally, Apple is probably going to release a new 4K 21.5-inch iMac, and it could ship as early as next week.

Check out the video above for all the big rumors from this past week.
