In an interview with Official Nintendo Magazine (Australia and New Zealand), Masahiro Sakurai, creator of Kirby and the Super Smash Bros. franchise, gave his thoughts on the 3DS demos seen on the E3 show floor. Of all the games he saw there, the Resident Evil 3DS demo impressed him the most, stating that "The Resident Evil demo was very impressive. The real time graphics in that are very impressive and I've already seen things that I can learn from that."
Sakurai is currently working on his first 3DS project, Kid Icarus: Uprising.
