I think the difference between myself and dissenters, is that I'm of a realistic understanding of what success constitutes. For example, I'm pretty sure some of the bigger posters on here have called psp a failure, and while vita hasn't exactly done psp numbers, there's plenty of time to improve.
Again, I will ask, would there be a thread if Sony had cut the price. Let's pretend Sony did have enough money to cut it safely, let's pretend these excuse variables didn't exist. Would there have been a thread if Vita had dropped in price previously to selling what 3ds did. Yes. Yes there would.
Even later in its life, even if it becomes more successful than the psp, I imagine there will be all kinds of excuses to continue trolling it.
