Hard to say. The last few big NJPW names have made Impact/TNA runs right before their contracts expire (Switchblade, Ospreay, and Okada).

My gut feeling–and it's nothing more than that–is that TNA and AEW aren't on the best of terms. Maybe it was TK’s commercials, the way Sammy was handled, or something else, but I just feel like they aren't too cool with each other right now. For a company that's all about the forbidden door, you never hear AEW mention Impact/TNA.
