Capp,
I recently booked a SavanView studio at AKL Jambo for 6 out of seven nights two months out for the end of April, first of May. I would think that to be comparable to mid-January. As I have been looking to get that last, seventh night, OKW was available for Thu-Sun up until about a week ago. At the time of this typing, the fulll week is still available at SSR.
I have not stayed DVC points in Jan or July. I find it hard to believe that somone on top of their planning could not get 1BR at WDW by booking on the very first possible hour on the very first possible day at the 7 month window of the seasons you reference. At that moment, all are equal. You could have paid $180/ point at the GF DVC, or $40/pt for a closet in maintainance building at SSR. You are treated equally.
Especially likely is a 1BR. It is my beleif that 1BR's are the nomansland of DVC. If I have 4 people, I am likely to get a studio, as it takes less points, I can stay longer, get better views, go more often, etc. If I have more than 4/5 people, I will go 2BR for obvious reasons. Therefore, 1BR appeal to a smaller market: "I have 4/5 people, I have points to blow, but not enough people or points to go 2BR." I realize this is a generalization, but if we are using the law of large numbers, it applies.
For a more concrete answer, I just checked availablity for mid-July for a 1BR on the website. Available: 1BR Std view and Pool view at Boardwalk. (Standard view at Boardwalk is a great deal, and hard to get I am told), AKL Savannah view, Wilderness Lodge. This is about 3.5 months out.
Now, you didn't ask this, but I will caution this. Dues at the beach properties are high, and have the greatest potential to get really high (storms, insurance, property taxes) IMHO. A large contract would be hard to sell already, as others have said. What if the dues started to skyrocket? could you get stuck?
The beach properties have always appeared to me to be an up front savings at the expense of longer term cost. Weigh that carefully.
