I expect to get the Performance Kit because I could use RC-N3. I am hopeful some of the non-standard accessories are compatible based on overall size and fit but I don't expect batteries and filters to be compatible with NEO1 but RC/MC/Goggles and mounts and cases and other attachments......
For the US, we'll need to continue to rely on our eBay partners to come through for us (again) but if you want MSRP, it might be worthwhile to wait for a few sellers on Amazon to sell a small lot of "subsidized" drones to get the channel jump-started before the bloated prices kick in (ala Mini 5 Pro). Either way, the US is being taken advantage of but....it's a free market.
