I'd be delighted for you to be right, but I think I see other ways they'll be able to justify.
Put 2 bathrooms in 1 BR villas, 3 bathrooms in 2 BR villas (to explain why the points are more than RIV).
Keep the 5th sleeper in the studio (which, among MK resorts, is only found at VGF - I guess maybe the OG PVB studios too? I know it isn't in PIT/BLT/CCV/BRV studios).
Maybe make the GV even larger than VGF's (and definitely larger than RIV to justify the higher points there).
Sell the lazy river hard - the first lazy river since Beach Club, can you believe it!
Especially if they combine with CFW, they're going to need to have a lot of points to spread out those costs and bring down the dues which, as you point out, the A Frame cabins will surely eat up a lot of those. We'll all look at it, just like we look at the PIT point chart, and think, wow, that's a lot of points. And, it will sell. Presumably RIV will be sold out before LSL opens. Then, after PIT sells out, it will be the only WDW resort in active sales.
Of course, at a minimum, I don't think the points chart will be anything like the points charts for CCV 2 BRs and under which, for me at least, makes CCV all that more compelling. And, I'm guessing we won't see CCV go on direct sale again while LSL is in active sales. Oh boy, there I go again finding reasons to justify buying some direct CCV points.
