Pictures from early sales copies of the January issue of Newtype, on sale 12/10, reveal that the "new project" teased in last month's Newtype for Fate/Zero is nenpuchi figures that will be released with Newtype. The same blog that posted the teaser image last month has posted this picture of a Nenpuchi Saber in a swimsuit from the January issue:
While details are scant, Newtype will be including nenpuchi figure(s) designed by Type-Moon's Takashi Takeuchi. Nenpuchi is the short for Good Smile Company's Nendoroid-Petit line of figures. It isn't clear whether one figure or many figures are planned from the current information. Further details are going to be revealed in the February issue of Newtype which suggests the figures won't start being included until the March issue, which goes on sale 2/10, at the earliest.
