It clearly says in that picture and on the website that the SIC 15th Anniversary figure will be Shin Ichigo; emphasis on the "Shin" (new).
The article in the picture goes on to talk about how SIC started in 1998 with Kikaider, then Bijinda, and continued from there; how the Kamen Rider SIC series started in February 2000, and has gone all the way up to the upcoming release of Kickhopper and Punchhopper, Volume 67.
I'm not completely sure what the LIMITED part is about, but it's got nothing to do with Shin Ichigo, as far as I can tell. I believe it may be including the limited edition (exclusive, such as Tamashii Nations) figures as part of the "more than 100 SIC releases" thing.
