Although we've known for quite some time about the Sprint Motorola Xoom and Samsung Nexus S 4G, one thing about both of those devices that still eludes us seemingly is the launch date. We've seen some rumors here and there but overall, nothing official has made it out. That said, the latest Sprint playbook now has employee training dates listed in it, which leads us to believe launch is only just around the corner. Hopefully after "school" gets out, we'll have a more specific date for you all but until then -- we're fine with knowing things are still moving for both these devices.
