Well, I don't know about Fran, but I need more than just a new bell or whistle to jump ship. As you remember, I skipped the entire V/VA series while I had my G1000, simply waiting for something RADICALLY different, not just an incremental improvement.
If Roland's NEXT G-series is merely as gradual a creep forward as Yamaha's model improvements usually are (to be honest, it seems that even they are only willing to make a great leap forward every ten years or so... Mega Voices, SA, etc.) I will probably be skipping it.
In the meantime, there are LOTS of people happily playing T2's, PSR 3k's, PA1Xpro, etc., not to mention T1's and earlier, so I feel in good company with those that don't feel an urgent pressure to jump ship every new model comes out.
It ain't just me and Fran, you know!
