This is a bit confusing. Their staff said that the internal storage can't be upgraded nor did they mention anywhere than there's an M.2 slot, let alone a 2230 form factor. Expandable storage is only via micro SD, according to them, which was kinda suspicious since the I/O for modern (and upcoming) games would suffer a lot in that instance.
If this source is true (Gabe does respond to a lot of fan mails) and we end up getting the top end SKU with 512GB of storage, does that mean it will come with an on board 64GB eMMC + the 512GB NVME or just the 512GB of NVME, with the M.2 slot taken?
