..nothings happening, the article is a satire based on the increase of game developers making add ons/mods available for download for games, but charging people for doing so.
yes they did say it was a satire, but they also mentioned that some of them are already happening..
as for gran turismo.. that whole charging for cars thing is an internet speculation, but is likely to happen as they've split "Gran Turismo HD" into two games
"The biggest news on Gran Turismo HD is that the game will be split into two portions, known as Gran Turismo HD Premium and Gran Turismo HD Classic. The significant differences between the two "sides" of the game are extensive, not just in quantity but in terms of visual quality. First let's talk numbers. Gran Turismo HD Premium will feature 30 cars and two tracks, all of which have been modeled from the ground at a level of visual fidelity that simply hasn't been approached in the game before. As Yamauchi told us, modeling cars for the HD Premium version of the game takes roughly six months for each one, and the models themselves are composed of tens of thousands of polygons (as opposed to merely the thousands that compose those found in GT HD Classic).
As you might expect, the Classic version of GT HD will feature the "quantity" side of the equation--more than 750 cars, 51 tracks, and thousands of downloadable items. All of the assets in the game will come from data supplied from previous GT games, all upgraded for high-definition presentation. Essentially GT HD Classic will be a compilation of previous Gran Turismo games presented in HD quality. "
GTHD Premium - 30 cars and 2 tracks (high-fidelity)
GTHD Classic - 750 cars and 51 tracks (large amount of content)
I'm guessing if it takes them so long to model a car in GTHD Premium, that they're most likely gonna want cash for it
