The time to evolve does change, depending on how you play with Pleo. Also it depends on whether you are counting Pleo powered-on active time or human real time, and how you play with the Pleo.
MINI-SPOILER
(CORRECTION: during the older stages, the realtime clock does not speed up evolution.)
For the earlier stages, Pleo only counts time when it is running. When turned off or on a shelf with the battery removed, Pleo will not evolve.
If you want to speed up the process, more interaction and touching will help.
However, when Pleo gets to Juvenile, evolution is based on a realtime clock. Even if you leave Pleo on a shelf with the main battery removed, it will be aging.
(END CORRECTION)
Also, your experience with raising the first model may influence your behavior raising the new Pleo, not to mention your expectations.
BTW: The firmware may have changed, but for all versions I've seen, the thresholds have not changed. DISCLAIMER: I don't have the very latest, or any of the very earliest versions to compare to.
For the versions I have, the maximum amount of time at each stage is in this table:

> Also, everyone with the older PleoRB's, how long did it take for you?
My experience, when recording the amount of play time:
Playing with PleoRB constantly:
To Social Development stage, approx 3.5 to 4 hours Pleo running time. To Juvenile, approx 4 to 4.5 hours Pleo running time.
So that's about 8 or 9 hours (Pleo run time) until Juvenile, when PleoRB can start learning it's name.
BTW: After that, I left Pleo alone for most of the time. After a real-time week of infrequent use, I checked it again, and it had evolved to Adult.
