SY602 Transformer 4

Transformer 4 movie has been out since last year. Only now SY release their Transformer minifig, is it a bit out of time? I did saw SY released their Transformer minifig quite some time before from the internet, but it did not arrive to my place, nor did I see it at any other retail places either. Is this an old release with a new packing?
The printing quality is great, although very less color variance (metalic grey and yellow). An 8 minifig set, one of them is Golden Optimus Prime similar to Kreo's but with Lego minifig body.  Bumblebee has the face features from the T4 movie, unlike KreO's, Compare to earlier Transformer minifig releases, this is way much better, but some of the Decepticons and Autobots have quite similar heads.

Golden Optimus, Optimus and Bumblebee

Galvatron, Hound, Lockdown

Funny, DLP has a similar release. Even the side builds are similar. Is DLP and SY related???
