Yeah I get what you're saying. Like I said, it does seem like they made this decision long before the game was released and bombed, and probably for whatever reason had to stick with it. Maybe the "plot" was already written around the newer Spencer, maybe they already paid good money to have that design featured in the CG trailers/opening/ending/whatever.
Either way, it's not a huge deal imo, even though it is the black horse in the sense that it's the least popular Capcom design revealed so far, which effectively replaces a more popular one. On a slightly different tangent though, I missed the TGS announcements somehow, and I only found out about X-23 today. My reaction is utter confusion because it's basically another Wolverine character, except more emo and with tits. Why?!
