Marvell publishes roadmap of its ARM series called Armada

For those who haven't seen it yet, LinuxDevices published an article recently looking at the roadmap of Marvell's ARM line. The new line is called Armada and for Debian the Armada 510 (known as Dove) is of particular interest. To me, it essentially looks like a Kirkwood (the current platform) but with ARMv6/v7 (instead of ARMv5), integrated VGA and some other features. According to the article, the Armada 510 is aimed at "high-end smartbooks and tablets".

I'm happy to see the integration of VGA because I'd like to see more ARM based smartbooks, tablets and thin clients. At the same time, I'm worried that the VGA will be some proprietary chip without proper open source drivers and I'm surprised that the new chip only offers 1.2 GHz. After all, the current Kirkwood chip clocks 1.2 GHz already, so I'd have expected an increase to 2.0 GHz for the next generation.
