Hardware wallets include only keys. S10 will be a hardware wallet. So no blockchains. And no reason to "skip out" Bitcoin. No reason at all.
So don't just spread news rumors you don't understand, news meant only to pump certain coins.
I don't know, maybe the op is up to something. At least, there truly are articles by newsbtc.com and cryptodaily.co.uk about Samsung somehow supporting Ethereum and excluding Bitcoin. They are based on an unboxing video where the guy says it explicitly:
https://www.youtube.com/watch?v=9XWmczWFLts&feature=youtu.be&t=368. This customer could have just not understood the whole thing, though, I think it's not enough evidence. And it's based on pre-released version, so maybe it's just a temporary thing that they already made a working thing for Ethereum, but not for Bitcoin yet. For now we just have a couple of videos that show that only Ethereum is mentioned in the list of supported cryptos in the built-in crypto wallet. We have to wait for official info before jumping to conclusions.
