Both TLR for PS3 and FF Versus XIII are listed on Amazon.co.jp with the words "Tentative Name" next to them in brackets.

FF Versus XIII:

People originally thought that Amazon.co.jp only added "Tentative Name" next to FF Versus XIII, but it looks like TLR on PS3 has had it added as well. As I said before, it looks like TLR for PS3 is still coming out but will possibly have major changes/improvements over the 360/PC version. It may even be a sequel but include the entire original game on a separate Blue-ray Disc. Personally, I'm optimistic that TLR will come out for PS3. If it doesn't get released for PS3 then neither will FF Versus XIII.
