I can see this game and the TakeTwo announcement being related. Nintendo has probably known about the Take-Two's deal for some time, they would have people on the inside. With T2 leading the MLB bidding war, Nintendo saw that they'd have no MLB games on their systems in the future. So they release this now, so that they're established for when the deal takes effect.
On top of that, Take Two has a lot of money to recoup from the exclusive deal. If Nintendo's game does will, I'll guarentee you that WSB2k6 will appear on their console(s).
