Re: Was going to leave Samsung, now not so sure...
I think you mean the S7... The S6+ still doesn't have SD Card support.
Also remember that, at this point, it's all rumors and 'leaks'. Until official confirmation is out, there's still no certainty that the devices exist, that they'll have the claimed features, or even that the speculated release date will be upheld.
That being said, it's also smart to wait, if you can, for the devices to be announced. Why? Any direct competitor will be forced (usually) to offer sales, bundles or lower prices when a behemoth like Samsung (or Apple, for that matter) comes up with new flagships. So even if you don't like the new Sammy stuff, it's likely you'd find better deals on other phones.
