New Sidekick(s) headed to T-Mobile?

TmoNews is reporting that two new Sidekicks, or perhaps one Sidekick with two codenames, is set to launch on T-Mobile USA at the end of July. First out of the chute is the SK Gekko, slated for July 27, and hot on its heels is the Sidekick Aspen with a July 30th target release. There isn't any more info available and it seems a bit odd that two new models would be launching so close to each other, so for now we're just treating this as speculation.
