I doubt any games will be converted to 3DS. It seems like a lot of work for no reason. Besides, 3DS can play normal DS games anyway, so it doesn't really matter. The question we should be asking: when can I get me an r4 for the 3DS?
What? No. As far as I'm aware even an original R4 like mine will never work for the DSi so I see no reason why it would work for the 3DS. Also Nintendogs.
I don't think any DS games will be converted or be both for the DS and 3DS. No 3DS game will be available for the DS in any form or way, but the DS games can be played on the 3DS, but there will be no 3D effect most likely.
nintendogs and mariokart ds they will become: nintendogs + cats and mariokart 3D http://e3.nintendo.com/3ds/ note: you are a spammer, because you know this already jonez
Animal crossing 3D ;D Post Merge: [time]1278062990[/time] There are quite a number of 3DS games that is re-make form the NDS. There is also the Paper Mario Game.
And TLOZ OOT. Next up: Majora's mask, wind waker and in 2014 Twilight Princess (no, just joking but if it will come true: OMFG)
twilight princess will not be on the 3DS (maybe on the 3DSi XL ) the graphics are better then the 3DS will have
Well, I did hear of Shin Megami Tensei: Devil Survivor coming to 3DS, but I don't know if it's a remake or a sequel.
Jonez said he was joking...3DS games will not be re-maked unless a huge amount of people are asking for it, otherwise a sequel will be what you get ;D
