Rachel would be a better addition than Momiji-- and Momiji is my favorite out of all the Gaiden gals. From a technical standpoint, she would be a hard hitting brawler...
Kasumi/Ayane already have the Mugen/Hajinmon Ninja garb stuff down, but Momiji only adds more to that same premise. Rachel would at least bring a bit more variety in terms of styles. The only dedicated hard female hitter in DOA5 now is Tina...
And come on, we gotta give respect where it's due. She's one of the original Ninja Gaiden ladies. It was a shame she wasn't even mentioned in vanilla NG3, despite how bad that game was. Apparently she starred as a guest character in the Wii U version of Warriors Orochi, so the VA would have to had recorded some new dialogue for her. Here's hoping they put her in this DOA5++ as well!
If we're talking about variety, then wouldn't it be much better to add a completely brand new character? Neither Momiji nor Rachel come off as being new and original. Honestly, I would rather TN come up with something brand new instead or recycling old characters. Well Technically Rachel and Momiji are new to DOA, but there still recycled TN characters..
How about we wait for any further announcements on this new DOA5 project from Team Ninja before we start throwing tantrums amongst ourselves. Also it would be better if Team Ninja brings new characters on the sequel rather than in an enhanced edition.
Ever heard of Super Street Fighter IV? That brought brand new character to the series and it wasn't really a true sequel either.
Ever heard of Street Fighter III Third Strike? Because the some of those "new" characters are from SFIII as well as they're a couple of other characters from other Capcom franchise, the only really new character was that oily wrestling guy.
Nice try, but no. Juri Han is another that is brand new to the series.
I don't think any official info by Tecmo will appear prior to E3 in June
Well, like I said in the DOA5 Plus message boards that Team Ninja mentioned in Twitter that "supposedly" they were going to talk about new information this week regarding DOA5, but who really knows if they are.
