Tricky.
Switch has no games (I seldom care for first party offerings from Nintendo) and I am not seeing a good future in the short term/before E3 this year and longer term should have some indicators if it is going to pick up which I am also not seeing (EA, ubisoft and co are not saying much about it, and smaller devs are not shouting it). Probably won't sink to Wii U levels but again I am not seeing much. Likewise I am not seeing much from Nintendo that says they are courting new and exciting peeps in the indy world.
This also means Switch ROM hacking is of limited interest, and nothing has really caught my eye as something I as a ROM hacker could reasonably fix to make good.
Homebrew wise I am not expecting anything terribly interesting while android exists. Of course a port of android might change things -- if android devs can chuck in a Switch controls option then things can change, to say nothing of android itself providing a library of stuff already.
Emulator wise I doubt we are going to exceed the PSP for practical purposes -- yes yes yes your favourite special chip SNES game will run faster, and the sound emulation will be 2% more accurate (not that my non musical mind + concert+power tools+motorised objects damaged ears will ever be able to tell, and even if I could then would it really change the melody from bad to good?) or whatever but when enough of the 16 bit and older + PS1 library ran OK it is not going to get too much better. The N64 has aged terribly (a lot of it is almost unplayable to me today, especially if I have also tried the various ports and remakes things got), GC could be of interest but I have most of those sitting behind me as I bought in when the GC was cheap. Saturn did not have the most at the time but there is some appeal there, certainly would see a nice version of bomberman happen. Dosbox, maybe even as far as 3dfx and windows 95, if it could happen might do something, less hardware than that and a lot of it got ported to the Amiga and maybe 16 bit consoles too.
Softmod or hardmod means nothing to me. I tend to find hardmods more reliable, more workable and more future proof. Install wise I am what I am so that is not a problem. Warranties are not worth the paper they are printed on, much less the 120 minute premium rate phone call to even start to make it happen, though with Switch heat deaths possibly not being too far in the future I am the slightest bit hesitant there. Also some potential hesitation as I am expecting a switch lite/switch xl/new switch/switch SP... before too terribly long.
With that said I can write off a switch as an easily replaceable toy rather than something to be cherished.
I expect TX will release a fairly well realised hack vs the "bare minimum functionality/realisation of potential" and gated up the arse that we saw on the gateway -- if their profit is in the chip and not the firmware there is no incentive to block it too hard. If not then the levels of access granted will see it happen in the very short term, a la JTAG and RGH just being methods and the community then creates the modded dashboards/firmwares.
Bans wise. Reading this thread I am still shocked people have not taken to heart "hack and online is a risky prospect, never assume otherwise" concept -- I am sure we can find people banned from dial in MUDs because they hacked. That said with a paid but still Nintendo quality online offering... no loss there.
