develop and sell for latest consoles???

[iyenal]

what's the 2500$ for?

The development kit, a custom console that let you test your games on it with a special connection to the PC. Well professional things are always expensive, take the Xeon Phi for example. But if you want to develop a game for a console then you should have a minimum of investment and 2500$ should be little in that...

And that's the minimum.
