Looks like this will be a cool conference. I would suggest going if for no other reason than seeing Grabe and Warschauer speak.

My interests favor Warschauer, who I really idolized when I first started looking into learning technology for language instruction. Since then he has gone a little different direction, but I really think that he is one of the best out there when talking about the practical application of theory-based approaches, particularly for a near-novice audience.  I don't think that his talk on the new paradigm is going to be groundbreaking, but I'm sure it will be good (and packed, get there early).

If you are into reading/writing instruction, you have to have hear of Grabe as well.  I've never heard him speak before (and haven't read much of his work), but I'm sure he will be of interest is you are teaching or researching in those areas.

I went to this conference last year and it was very good.  The presentations were higher quality than many of the other local conferences and there is a little something for everyone.  Considering that this is a "Foreign Language" conference, it should be no surprise that presentations are given in many languages.  For the most part, you can probably assume (though not sure) than presentations with English titles will (of can) be in English.

I'll be there, so let me know if you will be too.  See the attached .PDF for more information (largely in Korean, so get someone to help you out if that's an issue).
