Update: Every stainless steel model is now completely sold out online.

We noted last month that Apple Watch inventory was shrinking ahead of Apple’s expected fall event, and now it appears that almost all stainless steel Apple Watch models are sold out online and in limited supply in stores. Only one version of the steel Apple Watch is available to order online, and seven of the aluminum Apple Watch Sport models are sold out as well. This could mean a few things for Apple Watch 2 news at Apple’s September 7 ‘iPhone 7’ event.

We’re expecting Apple to introduce a new Apple Watch 2 with a faster processor and an embedded GPS for mapping workouts and using Maps, but it’s unclear how soon new models will hit stores. Depleted inventory this many days before an event and possible launch date suggest Apple Watch 2 could be available in stores earlier in the month rather than several weeks after the announcement.

Apple Watch Sport is also more available than the pricier Apple Watch models. Out of 16 Apple Watch model, only one model can be purchased from Apple’s website for delivery. Seven versions of the Apple Watch Sport are also sold out online, which leaves 15 other options that are available to order for delivery.

This could suggest that first-generation stainless steel Apple Watches are discontinued while Apple keeps older Sport models around to hit a lower price. Even if we weren’t expecting a second-generation Apple Watch, depleted inventory of certain models could also mean that Apple is simply changing up the bands offered or awaiting watchOS 3’s release to ship models with the latest software.

But there’s another aspect to consider. Analyst firm KGI expects a new Apple Watch 2 and a modified Apple Watch 1 with a slightly faster processor. That means two new Apple Watch models: one with several new components including a GPS and a much faster chip, and one with the existing components and a somewhat snappier chip.

If Apple does introduce a totally updated Apple Watch 2 and a slightly faster (and cheaper) Apple Watch 1, that doesn’t leave much room in the lineup for further discounted Apple Watches that haven’t been refreshed (and the lineup may be confusing enough already).
