Until we see some specifics, I'm not sure what the big deal is. It was predictable that the tooling would eventually land somewhere.
While I've tended to buy more MTH items than Lionel (price, and too deep into DCS), the range of MTH models seems to have stagnated in recent years. How many more of the same models in different paint schemes can the market absorb? IMO, what is needed is some new tooling for different models.
