So I've got a New 2DS LL now (photos here). However, I've noticed that this New 2DS LL came with a firmware version that's currently not available yet. Although the firmware is still part of the 11.x series, it's still one newer than 11.4. I can't verify which one exactly, but Dev Menu shows 0.25.18. Firmware 11.4 is 0.25.5, while 11.3 is 0.25.4, and so on. While I didn't try to install an CFW on it yet, neither I tried any other hacking on it, I did try to run an older version of SystemUpdater (which should usually downgrade the firmware), but it gave me an error while trying to launch it. This serves as a hint to the inability to downgrade the firmware. I hope this helps to those of you who want to get this device at launch. I wouldn't say to not buy it at all (it really is a lovely device), I do advise the average Homebrew/CFW user to wait a bit longer.
