The Spike system seems like an odd side-step to me. There are some minor improvements, but not really enough to justify breaking compatibility and making people repurchase everything from scratch.
In contrast, Mindstorms replaced the old LEGO/Logo system (which I was fortunate to use in high school), and was a big step forward in a number of ways most noticeably that you didn't have to be tethered to the computer.
