The only game I know that followed your strategy Hisho is Resistance Fall of Man on PS3. There were additional maps for multiplayer available for download a few months after the PS3's launch, for a fee. Now they are free to download, which I have done. However I doubt I'll be playing them.
I agree with you that the Pulse packs should be available worldwide for free, as I doubt that keeping them locked for only a dozen person on this forum to buy will bring a lot of revenue.

Sadly, look at how much pages there are in this thread, and AFAIK we've been complaining since the beginning that they were available only for Europe. It didn't work, obviously...
I'd download them in a heartbeat if they were available to me, and the price reasonable. But they're not.
