Load of poppycock. No bricking has or ever will occur, stop with the fear mongering.
The Gateway doesn't go online likely due to a restriction in the Gateway itself - the developers mentioned that they don't
want users to go online in their FAQ releases. There's nothing that'd stop the Gateway from going online hardware-wise so it's most likely a software precaution as to prevent the Gateway from getting banned
(there very well may be differences between how a normal cart is read and how the Gateway is read and those differences could lead to a flashcart ban as far as online in concerned - not something the Gateway team wants to deal with before they investigate further into the matter).
yep ill be buying y and a whole separate 3ds(maybe 2ds) to play pokemon XD
And why would you do that? There's no way for Nintendo to establish whether or not you ever used a flashcart and even if there was, there's no way for them to ban you or suspend you as the base infrastructure doesn't support that functionality. Some titles are exceptions, such as Mario Kart, but other than that you're perfectly fine as it is. Getting a new system would be a waste, really.
Upon further inquiry I can see your point - you want to keep one machine on low firmware to keep the Gateway bootable and another up-to-date to play new original games - fair enough.
It's made to be tougher. If anything, it should break LESS easily.
That's what they tell you - we won't know until we actually get to test the system. The way I see it, it's just a budget version of the system without the 3D and with a terrible mono speaker, meaning it's Nintendo's version of the PSP E-1000/PSP Street.
It's actually written on every game case that if you modify your console or use unauthorised devices to play on your system, the game and/or the console could be rendered unusable. You're being warned beforehand, and then bricking (if it someday gets possible) is the consequence for that.
Don't extend what you're being told beyond what you're actually being told. What this notice means is that if for example you use an AR Code and that code is buggered, it might influence the game, for example freeze it and indeed render it inoperable. If you use an unlicensed cartridge and that cartridge is buggered, it could damage your system. If you shove a soggy toast into your 3DS, you might damage it. It does not extend to bricking or otherwise destroying the hardware
by Nintendo which is
illegal and will not happen
ever.
There's a big difference between goods and services. When you go into a store and buy a games console, that console is
yours and if you feel like it, you can shove soggy toasts into it to your heart's content. A
service on the other hand is not something you own, it's something you subscribe to and have to follow the rules of in order to continue using it.
With a service, you practically sign a contract and have to follow it in order to use it - you do no such thing when you buy goods, for example a console.
This is why you
can be banned from an online service for not following the rules but your system
cannot be harmed regardless of what you do with it.
tl;dr you can get banned from services as you don't own the service, your system cannot be bricked because you are its legal owner.
