I'll be honest, and I am quite possibly alone in this. But I don't mind any of the things they announced so far. For me, used games have never been a huge issue/system seller. I have more Steam games than I can probably play, but I have bought them throughout the years with never the intention to resell them, knowingly that I will lose the money if they ever go offline.
The 24 hr check in I can live with. Yeah, if my Internet goes down for a few days, or Xbox Live is down, I won't be able to play my games. They way I see it personally, it's a sign from a higher power that tells me to go outside, read a book, or do something else. If I can't play one week out of the year from these interruptions, that one week that I might not be able to play won't deter me from the other 51 weeks of gaming that I would be enjoying.
I understand that MS is aiming for a higher tier of consumer. They don't care for the consumer out in the middle of nowhere who has a bad Internet and borrows games from others, they aim for the one that has a great connection and buys new. Is it unfair, yes, but they aren't making the system for everyone, just for everyone under they target audience. Unfortunately, consumers will end up paying more. I do not trust publishers to lower prices and pass the saving from a no used games market to us. No, they want more $. That's a much bigger issue for me, games should have a wider pricing structure, not every game is a $60 game.
My only real deciding factor was never any of these details. My two main things that will decide what system I'll get are:
1) what type of online subscription service you will have, what will it offer, and what will it cost me,
2) what is the standard price of the systems.
If one system (either PS4 or XB1) is $399 and the other is $499, I'll get the cheaper one. If one offers free online mp and the other doesn't, I'll go with the free mp. If they both charge the same, and cost the same, then it's the software that sells me, nothing more. All this is smoke screen to me, I want to see the games that I will want to play this year.
