Seems this is the link. I hope they turn out good and aren't too pricey, i think it's a shame TakaraTomy hasn't continued this line.
I have a WST Slag and Grimlock. They're pretty accurate for reduced size knockoffs - the plastic seems a bit cheap, and not all the weapons fit into their respective holes, but for the price i paid, i think they were worth it - but wouldn't pay much more (i paid about $15 each).
Regarding Takara's Hybrid Style Transformers - i have both and they're some of my favourite toys. THS-01 Galaxy Convoy or THS-02 Convoy are
not shrunken down versions of any other Galaxy Convoy or MP Prime. In many respects they are more detailed than their larger versions. On the negative side of things, they do have fiddly transformations (to be expected at this size), and THS-02 has an unfortunately misaligned cab front in truck mode. His trailer on the other hand is excellently detailed. Overall i would highly recommend them as display pieces - they don't have the playability of a Classic toy for instance, but they just look pure quality in terms of materials and paint job. They were hard for me to track down a year ago, so i imagine they will be even harder to find now.
