Default Any Flex users thinking at all about the S5 or M8?

I love my curve (Flex) and I know it's way to early to even think about another phone but being the phone junkie I am it's hard not to. Just wondering if any Flex users thought about trying a S5 or M8 when they come out? I doubt I would get another phone but I did get a good deal on my Flex and or have a jump to use so I wouldn't be spending more money. I used a S4 for about a year which is long for me. I'm just not feeling the rehashed design. I liked the HTC One, so I would probably like the M8.
