Imho there are other bugs waiting to be put to use (remember the end of
this?), but probably we won't see them until the end of production.
And if we really need an hardmod to enter ReCoveryMode I don't understand how they are supposed to repair the software-bricked units without extracting the Nand chip...
there will probably be a similar method of entering RCM mode, the exploit came from a bug in the code of RCM mode that allowed signature checks to be bypassed, the "patched" switches can also enter RCM mode, they simply cannot be exploited, i would imagine nintendo have some "new" way of triggering RCM on the switch lite consoles, i would imagine something similar to how the 3DS had NTR booths, i.e if you hold a certain button combo and have a special cart inserted the console will enter RCM mode.....but it depends on if they even care to do board recovery, afaik pretty much any 3DS that went in for repair with a firmware issue was simply swapped out for a new motherboard, they might just prefer to strip the board out, swap it, then send all the dead boards to china to be fixed via test points and have no external way of activating RCM
from what i can see they switch lite is also using the same old analogue sticks, this would obviously be a greater issue if they end up suffering from the same stick drifting issues, as you can no longer just buy a new joy con and would need to either send it in for repair or open the whole console and remove the motherboard etc to swap them out
as for the "better battery life model" here is a better picture of the board,
kinda interested in the internal code names, VALI = switch lite, ODIN = revised original switch
so we have "Odin" and the son of Odin "Váli", funny to see nintendo go with norse mythology code names
Oh, and another note, is that a 64GB eMMC chip i see on the switch lite, not sure if any mention has been made on the emmc specs of the switch lite, but from what i can make out it seems to be a 64GB chip
