I'm really curious to see what the hardware specs will be. For it to be considered a "Hero" phone, it will need to significantly bump up specs. This is in light of the GS4's release from n May. I'm thinking quad-core, 16, 32 & 64 gigabit options, all having microSD slots to support up to 64 gigabit microSD. Upgrading the camera sensor that would be on par with the GS4's camera or better. Until recently, the Nokia 920 seemed to be king of the camera phones in certain aspects.
Screen size should be between 4.5 & 4.8 inch screens. For those who don't want the larger screens due to preference or smaller hands, Nokia could release a 4.3 inch variant, with the same spec offerings. Couple all this with that aluminum body that they've been talkin...
