MS has a large number of patents and engineers on staff , they are actively developing both software and hardware tech. If a memory company could benefit from any of that I don't know , that would have to be for them to decided. Nintendo has large amounts of money (like MS) and could of course bring that to the table for R&D and fab capacity.
As for Sony I was responding to Mr Fox pointing out that the xdr company lost billions . But that is what sony has done for the last half a decade + . Cell utterly failed and Sony invested billions into fabs to build cell that they sold off for a song and dance and the ps3 itself was a failure compared to their past consoles along with the failing pc business , failing tv business and other failures of sony from the last few years. Its not joint ventures that are bad , its sony's own choices to invest in niche products that don't have the demand that nand would have.
