Roland will demo their EXR-3 and EXR-5, which is already available in Europe and in Canada (surprised about that one). Would be great if they came out with an EXR-7, but I'm not predicting this.
I don't know if Casio has a booth at these shows, but if they do, they will be demoing their WK3000 and WK3500. If they don't show up at the show, then even they consider themselves to be a toy manufacture not a serious musical instrument maker. Sigh.
Yamaha will demo the PSR1500, PSR3000 and Motif ES.
Will Ekco show up with a real product or be bankrupt?
Korg will demo the PA1X PRO.
