I'd imagine so. I've bought two of them from Walmart already and have seen sideswipe and silverstreak specifically at Target so since they're in the same wave they've been around in at least my area.
good because im LOOKING FOR IRONHIDE!!! im calling target now. dang i forgot to ask about magnus and they said no to ironhide and im calling another target now and im going to ask about ironhide and magnus....
I saw a Sideswipe at Target recently, and since they're the same wave I would assume Ironhide could be found there.
The wave is still pretty new so it might be hard to come across Ironhide since there is only one per case. But give it a little more time and you'll start seeing them more and more.
Only Walmart, that's been reported anyway. Not to say that it couldn't be at your local Target but it's not on their website.
I found all of Universe wave 3 at my local walmarts. I would imagine that the case has made it's way to target's as well though.
The only place I found Sideswipe and Bluestreak was at Wal-Mart. I'll be keeping an eye out there more than I will Target, at least until Target starts stocking up.
