Nah, as someone who owns a ton of both I can confidently say that'll not be the case.if NG is ever becoming JC, it will be not as good as JC since JC has better prices, better configurations (FDs, Interactives). While NG has slightly better molds and printing, which JC doesnt fall too much behind.
Interactives are gimmicky toys, not accurate models. Disregarding likeness for individual types(which NG is generally better at anyway), NG's moulds have better-proportioned aerials and crisp, well-rolling gears across the board. Their solid-core engines properly replicate fan blade shapes. JC's surface finishing feels somewhat flat and they consistently screw up printing, particularly the cockpit windows and colors. Known issues are never fixed with JC, while NG does make changes (CX Tristar, Alaska 737). And JC's QC is, to put it lightly, nonexistent. There's a huge difference if you actually look close enough.
As someone who collects certain Asian majors JC's releases are definitely better. But it really doesn't matter because I'm rarely ever satisfied with a JC, so I pass and wait for AV400 or NG.
