The reason there is a limited selection of characters is because there are humans who have to make those characters. They carefully model each character and give them a unique and original moveset. It takes time and money. In the production of one game, they can usually only build 10-15 characters. That's why they carry over the characters from the last game and stack new ones on top. There are nearly 50 character in PW3 and there'd probably be 65 or so in PW4.

Your answer to 'better replay value' was to just add more content, which again, they don't have the time or budget to do. And why would you want that content to be DLC? You want to pay $100 to get a full roster?
