It was great this year. There were DS's and DSL's in lines all over the place. Last year, I only saw PSPs. This year, I only saw DS's. The only part that upset me was that I forgot to pack my charger and only had about 10 hours of play with my sexy DSL.
It's nice to see that the DS is definitely more popular, at least in the anime crowd and I'm guessing it'll take over the general public soon as well.
