Quoted: Other developers chimed in to express their dissatisfaction, too. One developer claims he's only going to wait until the end of July, then he's switching to iPhone or Windows Mobile. Another says the developer community is falling apart, calling them "Google roadkill." A third notes that by the time a new SDK ships, many of the developers will have already released software on the iPhone platform, noting that it's "a platform with 20+ million users versus ZERO user install base for Android. It's not a hard decision to make after all. Hopefully someone wakes up sooner than later."

Likewise, China Mobile could see a launch of its first Android phone pushed into 2009.

Both Sprint and China Mobile are also said to want to make their own branded version of the platform, something which will take more time and resources. Sprint also is unsure about whether to push forward with a device that works on a 3G network, or simply wait until the 4G networks are ready to go.

That is not a good sign.
