Not developing as in starting from zero, but developing as in taking an existing platform and modifying/improving it for a new series of cars (in this case simplifying the platform to make it cheaper to produce, and targeting the very lowest end of the car market). Admittedly not a platform we're likely to see in 'the west', and sure it's nothing fancy, but I guess you have to start somewhere.

edit: reading back through the original thread, I agree that you are correct that Skoda is not developing a ground up platform that will be the basis for several VAG cars.

And it definitely isn't something which VW uses to base their own cars on.
