2. All three either have no moveset potential(Gex and Abe) or they won't bring anything new to the table(Tomba).
3. They're different and unmarketable. Which sounds more appealing to the average consumer? A badass like Kratos and a Psychotic clown like Sweet Tooth or a wise cracking gecko, whatever Tomba is, and a skinny...thing in a loincloth? In today's market those three would be laughed at.
4. They'll stand out as unmodernized characters from the past which will turn off a lot of people.
5. Only hipsters want them in.
There. I basically deconfirmed three characters for you all. Good day. --- http://w11.zetaboards.com/New_Super_Smash_Pros/online/ Looking for a fun place? Go to New Super Smash pros.
