wondering if you will be offering the Nexus 5x with 32 gb
We will only have the 16gb version due to its popularity. That said here are some way to carry around more stuff: https://recombu.com/mobile/article/how-to-add-extra-storage-to-nexus-5x-nexus-6p-memory-card
The 5X isn't quite a high end phone but it's close. 16GB should be fine for most users who take it. But if not, I recommend just using the extra money to take the 6P instead. It's a larger phone, sure, but it's got the better display, speakers, battery life, metal design, and comes with 32GB storage you're looking for.
