bioware will never do kotor3 no matter how much anyone wishes. they are elevated onto doing only their own games now (jade empire, dragon age). hell, they don't even need the d20 system anymore.
kotor3 will be made, but bioware will not be involved. you can take that to the bank. obsidian may be devloping it in secret right now (or not i have no idea).
the real $$$ comes in developing games that are devoid of licensing issues and profit sharing. at least, that is what makes sense.
