Ballpark date -- this depends on 2 items. SEAS production (they are always a bit slow and they are on holiday right now until Aug 2nd and how we ship the parts... Shipping from Norway by ocean typically takes from 3 weeks to 1 month.
If we ship everything by air (which is an option), the final cost of the upgrade will increase by what I estimate to be between $5 - $10 each, to cover the huge expense of air-shipping this many parts. When all parts are ready and I can evaulate the cost of both shipping options, I will probably let you guys decide by which method we ship. Air-shipping will certainly shave about 3 weeks off the wait, but it will cost you (and us) a bit more.
