From my previous reviews of S4 cases from Spigen, including Neo Hybrid (which btw - make sure to purchase ONLY from Spigen directly on Amazon or eBay store, you will see a ton of knock offs within days from CH, Spigen manufacturers their stuff in Korea), it does look sharp and offers an OK protection, but NOT the best protection because they make lip to be too shallow. It barely covered a thickness of their own tempered glass screen protector and they had 2 versions of screen protector, one with a reduced thickness.
Reduced bezel will be a challenge in a design of the case. Tempered glass is one of the best options for display protection, I had my VITREO on Note 2 since spring time and can't imagine any other way. Just my opinion, which is based on a ton of my own reviews
Without a doubt, Spigen cases and screen protectors are TOP NOTCH, but keep in mind that you could be locked into their ecosystem because from S4 experience other tempered glass screen protectors didn't work with Neo case, and even some regular quality screen protector were a bit too tight on the edges. Don't know if it's going to be the same with N3, but my advice is to not rush into plopping premium pre-order price but rather buy a few $1 TPU cases from ebay to hold you over once you get a phone, and do more research once a phone is released to compare other cases and hands'on reviews. In general Spigen, Seidio, UAG, Case-Mate, and Trident will be the way to go.
