I'd love to see an Obsidian-made KoToR 3. Hell, I'd be happy with a remake of the second game that has the cut content from the released version. I thought Obsidian did a much better job overall with the franchise, despite the bugs and missing content.
The KoToR 2 remake may never come into fruition, but I can only hope otherwise.
I'm actually surprised this hasn't happened already. I expected a "KOTOR Legendary edition" to be released by now. With both KOTOR 1 & 2, a graphics boost (like they did God of War chains of Olympus), New content that fills in the gaps on pt2, achievements, etc.
They gotta know this would sell more than GTA 5 did..
