I mean maybe eventually, it's a plot point that kinda HAS to be covered since we know Warhawk IS The future because.. Beyond is 100% the canon future in the DCAU, but we don't know the exact time frame for him to be born though the guy looks like he's at least in his 30s IMO.
Hopefully it's done better here than in the Justice League Beyond comics from a while back where they basically Fridged Mari and Carter and had Johns Green Lantern ring taken from him all in service of doing that. There was quite a bit about that run I liked, the Aquagirl origin issue in particular a really really good Origin one shot story but jesus that Warhawk origin issue was a complete mess.
On another note the solicit makes me totally think the first arc is gonna deal with AMAZO finally coming back. Can't think of else that description would be.
