It's the same weekend as the Samuri Gathering at the Donington Historic Festival, so club support is behind that event instead of Japfest this time.
Don't know about Japfest 2; personally I'd like to do that too given I'm going to the Donington Historic. Bear in mind that the Japfest stands are actually organised by someone from the 350/370 club, and it's a joint stand for them, us, 300zx, etc. They may be planning something for Japfest 2 that we can piggy-back on.
