Think it's been confirmed not to have Lotus glass either, I know I've read that somewhere but can't remember where.
I honestly wouldn't worry, as you said, screen protectors feel just like the glass, even better with a few brands and they prevent scratches 100%.
I've always used Seidio screen protectors on my OG and I love the feeling, had the same one on it for nearly 2 years with zero scratches.
I have zero concerns about scratches, the only concern I would have if we find out it's not a decent fortified glass is if it shatters easily, but then again I've only dropped my OG once, so I'm fairly careful.
I do plan to go without a case this time though, so maybe I'll buy insurance=P
I think the point to take from all of this is, there are ways to prevent scratches if the screen isn't scratch resistant(which it is), anyone who says they don't like the feel and can tell the difference between a screen with or without it's screen protector, well I don't think you've used a quality brand because these things are perfect and it looks like Wrapsols is another dry screen protector that is well made.
