Not really. Street Fighter has had a good bit of success over the years when it comes to action figures, even going all the way back to ARAH. On top of that the brand is apparently strong enough to have two lines of similar offerings going at the same time. So going deep on the brand is not surprising to me, especially for Jada.
Invincible so far hasn't had much success with action figures. One wave of Minimates and what? 5 figures from Diamond? Oh and about 10 minifigs from some company called PhatMojo. Granted Diamond's money problems probably hurt the line and Jada has shown themselves to be miles better. I think Invincible has a great, large, cast of characters to draw from so I don't imagine it will be hard for Jada to go deep. It is more about is there enough support to get it past a couple of waves when only 1 company has done more than 5 characters to date (I think there is).
Also while I can see Super7 going with deep cut characters right out of the gate I don't think they are a good fit overall, mostly because of pricing and quality of their offerings. They work better when they are pretty much the only game in town and having Jada making what are better figures won't be good for them.
