I know your pain because I have been there before.(just like many of us have been)
By now this should be the end of the waiting time.
It is frustrating but it is what it is. Patience. I had to learn the same myself.
I got my DY about 2 months ago, but the SK I ordered is expected to come on the next shipment (to Canada) that is expected to be available by the end of this month of July. Is likely that your guitar is coming on this one.
Since I was showing up often to my local store where I ordered about the status of my order, I realized based on the way the representative talked on the phone to the distributor(the only one for Ibanez in Canada), that they were fully aware of "Those guitars". After realizing that, I stopped asking until I got the call to pick up the DY.
My guess (based on similar issue I have witness on other industries) is that the distributor might be giving priority first to their biggest/ or key customers and fulfilling those orders first, then filling up the remaining orders(coming on different shipments). It is possible that this is the reason as to why despite the arrival of a few LG in the past, they ended up going to other stores/customers even when you ordered around the time of announcement.
Also out of the 3 colors the LG is the one most people are going crazy over it, so there is competition to get them too.
Just have a bit more patience and we all really hope it does arrive by the end of this month.
It is worth the wait.
So please don't cancel or give up, now that it's arrival is imminent.
Let us know when it arrives
