Looks like the 3DS is here to stay, for now.
Nintendo in general are known to drop support for their older consoles as soon as their newer one is out- this has been true ever since the Nintendo 64 days, but that is not going to occur with the N3DS, as new report claims Nintendo will support it through 2018.
Emily tbe famous Nintendo insider is back again with some more new info, and this report claims she knows that even when Nintendo NX launches in March 2017, that it will not spell the death of the N3DS, infact big 'N' will be ramping up 3DS support and continue releasing new games and more 3DS color changes like the recent Galaxy model just announced, and this continued support will be thru-out fiscal year 2018, a whole two years of more Nintendo 3DS support after their new NX handheld/console hybrid launches.
If you have been skipping all of Emily's insider tips on the NX and what big 'N' is planning, then I suggest looking over her recap which is linked below, and afterwards we love to her your comments about Nintendo keeping up the 3DS support even with NX being out!
