Just a few minutes ago, we reported on Dell’s upcoming tablets Sparta and Athens in the 11-inch segment, courtesy of a leaked roadmap that Android Central got its hands on. We now have a rough estimate of when Sparta, Athens and the much anticipated Streak will launch in 2010.

It looks like the Dell Streak could debut as early as next month with Sparta in August and Athens sometime in Fall.

We also have a reason to believe that T-Mobile may be the carrier partner of choice for Dell Streak with Dell working with Vodafone for UK launch. There could also be a Chinese version of the device coming eventually.
