After a hiatus away from Twitter, Randy Falk is back and has been tweeting about the upcoming Alien Day (26th April) as well as giving hints about new reveals.
For Alien day the indication is that it will be something to compliment last years Kenner inspired Ripley Space Marine.
There is also the indication there will be some Covenant reveals.
On the tease front, this image has been teased. The common theory is that this is the head sculpt for either a Kenner inspired Panther or Crab Alien (as below) and will be part of another Kenner inspired series.
