I think January 2013 is going to be her best opportunity for Lakeside given her age, and the consistency she has shown over the last 18 months or so. She does have a couple of obstacles to beat first though:
1 - Anastasia is also playing rather consistently at the moment and she won't want to give up her title
and
2 - the biggest threat in my opinion, Trina has won the last two tournaments and is getting back to her best now, so she must be finally coming to terms with her mother's death just before Lakeside at the start of this year
Personally I really hope that Deta does win Lakeside at least once as she is a class act as Larry says.
