I really don't see Nintendo doing a major internal hardware revision with this thing.
Nintendo never did so with:
- 3DS XL
- 2DS
- New 3DS
- New 3DS XL
What makes New 2DS XL so special? The 3DS is nearly 7 years old, what would make them want to rewrite BOOTROM? Patching the potential of an exploit that could very well be done on EVERY other 3DS model at will, be it via software AND hardware?
I think at the VERY least, it'll have 11.4. For sure. Hardware revision to patch SigHax... eh, I sincerely doubt it.
Sorry, but by definition New 3DS/XL compared to older ones had a hardware revision.
