Back in 2013 when Wingnuts first announced the AEG and showed test shots of the kit they said that it would be released in 2015, so it appears the pre christmas release would have come a surprise to everyone, putting it back a few months just puts it back to the original release time, roughly.
I purchased a brand new unopened Gotha for $95, considerably cheaper than the advertised Wingnuts price, I made my purchase on eBay. There are bargains to be had, just have to be in the right place at the right time, I also picked up an OOP LVG for just over $100, a little more than the original Wingnuts price but still a lot better than what some kits have been selling for.
