So it looks like quite a lot of you were waiting on the Developer Editions for those new Motorola phones. Just over one day after Motorola posted the Developer Editions of the Moto X and the DROID MAXX on the company's official store, all three phones are unavailable. The Verizon Moto X Developer Edition is marked as "Out of Stock," while the GSM Moto X DE and the DROID MAXX DE are marked as "Coming Soon."
Motorola seems to have vastly underestimated the demand for these phones and their unlockable bootloaders, even at the hefty unsubsidized price of $649.99 for all three models. (It probably doesn't hurt that the Moto X models were the only 32GB versions available without buying a locked-down phone for AT&T.) That being the case, there's no telling when they'll be available for purchase again. Motorola's US factory for the Moto X in particular is probably using the vast majority of its manufacturing capacity for branded phones for AT&T, Verizon, and Sprint. If you managed to get an order in while the Moto X Developer Edition or DROID MAXX Developer Edition was still available, consider yourself lucky.
Naturally we'll be keeping an eye on the Motorola store for any updates.
Update 9/20/13 7:00am: The Verizon Moto X Developer Edition is back in stock as of 10AM Eastern on Friday morning. If you want one, get it while you can.
Update 9/20/13 5:20pm: The Verizon Moto X is gone again, but the GSM one is back. The Droid Maxx is still listed as "coming soon."
