Given the choice of a 2210, 2305 or a 4010, I would opt for the 4010. I have talked with Dutch about these, and he indicated that he really liked it as well. But also, that folks don't 'get' it. I suspect that 2210 sales really ate into the 4010, and imagine there are some out there sitting on dealer lots...
But what if buyers were presented with different options. The 2305 at a great new pricepoint, and the 2320 with more power than the 4010/4110 but priced between them? I believe most '4010' buyers would welcome a slightly larger and more powerful machine, complete with better forward visibility at a slightly higher price than JD would offer the 4010's replacement.
So, while the 2305 is no replacement for the 4010, they can cover their bases, save money, and pass some savings on. Does everybody win?
