Yamaha DTXpress/DTXplorer/DTXtreme

Hi, 
There are strong rumours that yamaha is introducing the DTXPRESS IV by 
July-Aug this year, at least in Singapore where I'm based. 

Grapevine reports that production will start in June'06. Specs 
unclear, though pricing reported to be marginally higher than current 
DTXPRESS IIIS. Info sourced from multiple drum hardware shops, incl 
Yamaha's showroom.

Does anybody else have any info?

Cheers
