wait a year and let them take care of the problems insteada buying it and complaining.
That's not going to happen. Whenever a new piece of equipment is released, be it a new video game system, phone, ipod, head unit, television, whatever, people are going to buy it no matter what. And if it has problems, they will complain about it. That's how it is and that's how it will always be.
There's no major difference between buying it now & waiting a year for a firmware upgrade and waiting a year for the unit... Besides, it doesn't effect you one bit if other people are buying it. So don't go judging them because they have different priorities than you do.
Besides, if you take the D3 as an example, if people had decided to wait a year and buy it so Pioneer would have a chance to work out the bugs, buying it now gets you the same exact unit with the same exact problems that you would have if you bought it right when it was released. Why assume it would be different with this unit?
Anyway, all the things I need it for (basic navigation, ipod control, high voltage pre-outs, XM radio...) the new unit has no problems with. It will basically be the same as my D3 only with better routing capabilities, much better sound quality using my external amplifiers, and a better looking GUI, and I don't have to leave the nav disk in the DVD drive. I don't care if the bluetooth doesn't work right or if the voice command is messed up or any of that, because I wouldn't have used them anyway.
