No, I didn't do the minicon ones, though maybe I should have. haha. Not gonna worry about it.
Takara is still making the 1st editions as far as I know. I don't have mine in hand yet, but my pre-order came in Tuesday and I've heard several people say they have theirs already (I was in the second round of pre-orders where as the others where in the first). The store is a little slow with shipping things out but they're reliable. Never had an issue with them in the past and never heard of anyone having issues with them either.
BigBadToyStore (the place I mentioned above) still has most of the 1st edition up for order if you want one. The only one that's sold out is Optimus, but I seem to remember hearing he got canceled. No idea why.
The store is a little pricey but they're still cheaper than ordering them from Japan. And far cheaper than ebay (last I checked anyway).
