Rumors of a Knights of the Old Republic Collection have been renewed as GameStop and Amazon.com have both update their databases for the bundle.
The collection supposedly includes LucasArts' Knights of the Old Republic and Knights of the Old Republic II: The Sith Lords for PC, both of which were released originally on Xbox in 2003 and 2004, respectively. The first received critical acclaim, but the latter saw mixed reviews due to its rushed nature; multiple fan projects have seen KOTOR II's missing content unlocked and restored over the years.
BioWare's KOTOR (the sequel was Obsidian's work) was actually released for Mac just a few months ago, via Steam. According to GameStop's records, the PC collection will be coming July 17, with a retail price of $20 USD. Amazon.com has also opened up pre-orders for something they're referring to as "Star Wars Knights of the Old Republic I and II PC Bundle Pack."
Publisher LucasArts, on the other hand, has yet to confirm any of this.
