Just so we're clear, it sounds like there's a lot more in the update than there really is. A lot of the updates being listed are for future releases or the main big 1.6.1 update it looks like. (Or were already released in previous releases.)
Here's the actual 1.5.1d update:
We know you're interested in details, so here's what's new in delta :
- New activity with Sadira at the Lady Luck Club.
- About 50 new top-quality renders.
- 9 Full HD 60fps animations with Sadira.
- Added tips to loading screens.
- Added dueling interface tutorial.
- Fixed minor bugs.
Since I don't personally care about Sadira, this update does basically nothing for me.
Personally I'm looking forward to more story with Penny and Dakota etc.
