I'm glad that they decided to wait til the 3DS was released to make remakes. This is mostly because of how uncomfortable I am with controlling Link with a stylus. Although I'm not quite as psyched as many others are with releasing a remake on 3DS. The large world of OoT, to me, seems like it should be on a non-portable console, because everything would seem to be condensed into too small of a space. Now, I am unaware of the size of the 3DS, but I don't imagine it's much bigger than the DS. The controls should be interesting, and they don't look like they'll be easy for me to get used to.
And as for the price, like Kazumi said, it won't be 300 bucks, it will be somewhere around 200. But that still is a pretty nice chunk, and I'm going to have to do some serious lawn mowing to pay for it. And just as long as it isn't Virtual Boy all over again, which is highly unlikely to happen, 200 bucks is actually quite a bargain in my opinion.
