This is a loaded question. It's like asking if I really want another meet & greet over a new attraction, or another restaurant over a new attaction or if landscaping and grounds work is more imporant to me than a new attraction.
I look at the total experience. To me, it's not just about attractions (I can go on roller coasters and spinners and themed attractions for a lot cheaper than Disney). So, do I think this RFID work and new FP system is "prefered" over a new attraction? I guess, yes, I do. As I think both are important to the growth of the experience.
I think it would be crazy if we were still actually using A-E tickes by attraction like it was 1975. I think it's also crazy to think the FP system is going to go unchanged from it's implementation in 1999. I look forward to carrying one item through the park for everything; ticket media, room access, charging, ADR's and reminders (DDP or TiW if applicable), FP, etc. Once everything goes RFID and all of my information stored in multiple places can be combinded - then that one bracelet, key fob, phone app, whatever will be all I need to enjoy my vacation.
You can't focus on only one thing. Attractions and e-tickets are important (as are C and D ticketrs so-to-speak). But so are maintaining the existing infrastructure, resorts, restaurants, non-attraction entertainment, technology, etc.
