One flaw I see in this whole "this was planned all along" idea - well, okay, a few. Nothing about this entire situation has felt planned.
If there was a specific production run and that's all they were doing (at least for a first batch), then there 100% should have been phrasing along that line - "limited time run, unless it does really really well!" or whatever.
If there was a specific number planned and that number was made, why didn't a reasonable portion of them ship to the international pre-sellers? Sure, you could argue that they didn't know what the international demand was like when they ordered parts for production, but they sure as hell had an idea by the time they were shipping things out.
If this was as planned, why did Harmonix have no idea it was coming, and why did it take a week to track down an answer?
If this was planned, why did we get conflicting answers from Fender reps ("we've decided not to do more due to manufacturing lead time", "we've sold more than we expected and wanted to go out on a high note", "we've discontinued it due to reasons we can't disclose"). If it were as planned all along, there should've been some sort of party line on this...
Regardless, the whole idea of this being as planned just smells wrong to me.
