Such a module wouldn't need to have ALL of the Integra's 6,000 (!) tones, but a good share of the SN Acoustic tones (more than the 22 of the BK-9) and good expandibility with virtual SRX expansions. But I don't think it would be wise of Roland to make it much more expensive than 1,500 euros, as the market of higher-priced arrangers is thin and due to Roland's weak position and image in this segment it may be too much of a business risk in their current situation.
