Agree 100%. If I can get all this for $149, it couldn't cost them that much to do it, and it would add tons of utility and expanded sound potential to the arranger kb, not to mention upping the fun factor 1000%. Oh, and it's not just the 'sounds', what about the unlimited (and possibly superior) FX (effects) that would be available without having to deal with additional hardware. Let's face it, VST's and VSTi's are not going anywhere and will figure prominently in future music production. And luckily, it is infinitely cheaper and more versatile than any hardware equivalent. You will notice that Bachus, despite having an awesome pallet of sounds as presented by the Kronos and PA4x, still chooses to expand that pallet through external software. Compared to him, I'm a total novice at this, but I'm still having a barrel of fun exploring this new sound source.
