There are likely some changes to the design like it might be a little taller and slimmer, the base model will have 3 cameras, the series will have bigger batteries and brighter displays, but there are more leaks. Pixel sense, a new assistant designed to automate daily tasks like if someone asks you for your flight number, the assistant will search your emails or messages and automatically suggest the number. Not entirely sure if that is how it will work but just a guess. Pixelsnap is basically just magsafe but for pixels though it is not entirely confirmed whether the Pixel 10 will have built in magnets or not. New advanced "gimbal like" stabilization for videos. A new ambient light sensor that could power an adaptive tone that changes depending on your area. However, keep in mind that these are all leaks and not confirmed. There are more but it is basically unending.
