It's why some things were New52 right away, but others stayed classic for a few years. The Rebirth suit was still being used after the Reborn suit came out, and the Reborn suit being used when they're back to the "new classic".
It's also up to the licensee. DC, if they're like other companies and I'm sure they are, sends a range of "accepted artworks" that can be licensed for use by the company doing the licensing to pick. One candy company, for example, had DC suckers for Superman, Batman, and Wonder Woman. Clark and Diana were New52, but Batman was 90's era, trunks and all. Explain THAT one, I dare ya. lol
But yeah - there are a lot of business factors that're involved with the whys and hows of that kinda stuff, and not really to do with "being current" or even any sense of market preference.
Hope that helps.
