The only preorders that have opened for new 2DS LL in Japan appear to be those of DQXI bundle.
2DS had a low price but also a terrible design and started with soft sales. In the end, unlike GB Micro's opposite course, that started strong and deflated very soon, it showed good legs and will have a respectable LTD for what it is.
New 2DS LL is the next real redesign with low price and a bunch of games the same week but with a LE bundle coming 2 weeks after its launch. In theory it could have a much better opening from 2DS but time will show the real impact it will have at 3DS total sales since it comes out at the twilight of its life.
