I have been waiting over 6 weeks for 4x #1 from japan, i called my dealer today and he said they have removed the ETA from the order (which was 19th november), which in his experience, means they might be either no able to fulfill the order, or they're not available anymore. I will update when/if i receive mine. The #2 parts have arrived but still took 4 weeks instead of the usual 2 weeks.
Hope this helps.
