I think it's reasonable to expect that we'll see a paradigm shift in the design, because we're in a recession and absolutely everything worth money is in a bubble because of the malinvestment caused by rampant money-printing. To that end, I would expect to see smaller, lighter Beys which will be cheaper to manufacture, package, ship and store. Being smaller means there's less space for gimmicks, and having less material limits what gimmicks can be made to function properly while standing-up to the forces involved in spinning at thousands of RPM and colliding with a similar object. If relatively complex gimmicks are going to be difficult to implement, then I think we would see two different things, firstly a concentration on performance and part variation, similar to what we saw in HMS and MFB, where we see many different parts, in many materials, but they're all mechanically simple so they can be made resilient. Secondly we should probably expect very simple designs right out of the gate, again similar to HMS/MFB where almost all of the first year releases were very solid with almost no moving parts. (recall that Customize Weight Disks came along relatively late in HMS lifecycle, and it was close to a year before the Hybrid Wheel System replaced the pure-Metal Wheels in MFB, for example)
So, in terms of similarity to MFB; I think there will be some clear parallels, but it's hard to know if there will be much metal in their construction, or if metal will be used for the contact points. I would suspect they'll be mostly plastic, because it's lighter, possibly cheaper, and it will break more often which could drive repeat business. (who knows, maybe the next generation is just Beyblade Minis?
