Nope it ain't. Try an xray. The worst IMHO would be schumacher. Cartoon squiggles all over with that annoying font. K is squarely in the middle, especially with regards to gear diff building. The forums/youtube are a godsend for that

So is it safe to say if I buy a kit that a shop got within the last few weeks that it will have the newer chassis in the kit?

nope. amain still has stock probably from older batch. I got mine from absolute also prob from first batch. My chassis held up nice to two weekends still.
Best is to contact dealer and ask them direct.

Only like 3 guys in here had the issue, and it doesn't effect performance. Your good either way.

You guys are lucky to get such a good support from Kyosho America. Down here, it might not happen but I will try my luck with the local distributor. I will most probably email Kyosho Japan and get them to provide the replacement.
