There's a lot of talk on one of the Fantom G forums that the Integra is gonna spell the end of the FG.
Basically it's everything people were wishing for in the ARX expansion concept, and some people held out hope that the RolandConnect teaser that was floating around for the Integra would be the long hoped for 'All SRX on one board' product for the Fantom.
I still love my Fantom, it is such a brilliant performance synth, but the little niggles like no SuperNatural Paino, no dedicated tonewheel mode (and really lame hammonds in the sample set) the loss of support for the ARX expansion format and no SRX option, and in Live mode a lame FX structure that won't let you chain 2 effects serially, (and to rub salt into the wounds the V2.0 of the Jupiter 80 OS added just that) still get me riled on occasion.
