Selling IP:s i good if you want to reduce your debt. That's why they usually sell them. Sony sold its IP:s for the reason of helping 3rd party (it was pretty good deal for Sony, because they didn't really lose IP:s). And Nintendo sold Rare, because M$ had bought 51% of it before, so even if Nintendo wouldn't have sold it, they wouldn't have been making games for Nintendo anyway, since M$ had the full control for Rare. It was pretty good deal for M$.
