Could Nintendo's humble portable be about recieve Valve's next online blockbuster?

It's been relatively quiet on the DS front as of late, but that's just changed with on of the juicier rumours of the year coming to light. According to the Australian ratings board, OFLC, the next-gen-only Left 4 Dead has been given a 15+ rated for Nintendo DS.

If the information is true (and ratings board's websites are usually a reliable fountain of facts), it would be presumed Valve's online, zombie-destroyer would have to somehow shrink itself into a game suitable for the system, while still maintaining a focus on co-operating with the world. We can't wait to see what the potential would be.

Keep it with N-Europe to see if this baby solidifies.
