Just saw this from AC, this guy attended the 2015 new Hasbro product meeting, doesn't allow to take picture, so he just described what he saw.

美版:美复G1铁甲龙、三尖头套装、闪电和大火车套装、录音机和感知器套装(磁带好像是钢钎和犀牛,感知器 的肩炮有特殊用处类似能看幻灯片)
Encore version (Platiumn?) tripticon, conheads, blitzwing & Astrotrain bundle, Perceptor & Blaster bundel
idw的大力神确实不错绝对泰坦级,因为是全年龄的所以单体的变形大家就别指望了,展示品都是手工未完成品 貌似肘关节不能动,组合方面下半年还有一个守护神,但只展示了热点感觉也一般。滑翔机还有一个紫色狂派重涂 不知道叫什么,同级别还有个战戟,还有几个没记住。坦克威确实不错还有个绿色。
IDW Devastator is indeed Titan class, but because it's facing all the age groups, so single robot's transformation is not much. The demo versino is hand-made unfinished product, eblow can't move. There is a Defensor will be revealed in late of 2015, so far only Hotspot is showed, and just so-so quality. Scout class has Warpath.
日版:会有很多D级人物,都不是主线人物所以没细看,ps擎天柱和md老威不错但站立有些困难。组合方面增 加电镀和还原单体成员G1配色。
Japanese version: (nothing important, I won't translate. )
MP:今年预计就发5个,mp25和某宝放出的预定款一样,配件是洛尔和收音机,大家去看看52集就懂了, 只看了灰模貌似可动性又提高了不少。21G没有斯派克改成飞行背包了比较坑,但官方介绍会降低 售价。
MP: This year will release 5 MP. And the MP25 is the same one as the pre-ordered on Taobao (I remember that Ironhide/Tracker on Taobao? Might be Tracker) It comes with "洛尔" ( a human?) and Blaster.
MP21G doesn't have Spike, but just a jetpad, the price will be lowered because of that.
