I personally didn't believe at first but seeing as he just realised bankai and - http://www.onemanga.com/Bleach/388/01/ - shows Ichigo surrounded by many blades (plus broken Hollow mask) which I'm just thinking "Gin released bankai, preview page for chapter 400 shows Ichigo among many blades, currently those two are fighting...."

All of it either adds up to multi blades or just coincidence.
