Before we start throwing "stupid" at you let's think this through for a few seconds:
The Pi Foundation could have announced that they were going to develop a new Pi with WIFI and Bluetoth, oh and 64 bit cores!, when they started development. Say 6 months ago or whatever.
What do you think the result of this might be?
Many people would immediately change their minds about buying a Pi 2 and decide to wait for the Pi 3. Like yourself for example.
Sales of Pi would drop dramatically. The foundations income would plummet. People would loose their jobs. Development of the Pi 3 would be cancelled. You would not get anything! Disaster.
Worse, what if the Pi 3 development failed for some reason? Perhaps that new 64 bit core was hard to get working, or perhaps the FCC failed the radio tests. The whole project could have been delayed or even cancelled. So now we have no sales for half a year plus no new product on time. Bankruptcy and misery all around.
Do have a read about the Osbourne Effect to get the idea: https://en.wikipedia.org/wiki/Osborne_effect
So, perhaps not "stupid" but certainly sounding like that 5 year old who was quite happy with his Christmas present but started whining and complaining when he saw is new younger brother got something a bit better
Anyway, be happy with the Pi 2, it's a fine machine, that's why you bought it. And good luck with your studies.
