Not to sound pessimistic but I don't think Kuu will release anymore new material this year
If not , her new single details would have been announced before the WALK OF MY LIFE DVD/Blu-ray if not co-currently on the same release date
And airfares to Japan during December ain't cheap for me . I spent almost 1,000 bucks last year when I went back Tokyo at the last week of the year/month
On off peak periods , I would pay probably 700 bucks for the airfare if I go Japan
