There seem to be a lot of people; both in this thread and multiple other threads discussing the Vita's price; talking about how it has been this cheap for ages now and how they bought their Vita for this price already.
So, genuine question now: Does anyone know how Vita's price situation has been in Japan? Is it regularly discounted to below ¥20,000? Have there been any temporary price reductions similar to Black Friday for the USA?
If the answer is no, then that means the price cut is going to have more effect over there since they just haven't been used to seeing those prices.
If the answer is yes, then this post by BaldrSkies pretty much sums up the effect. If retailer reductions were already making it to as low as ¥20,000, then a reduction in MSRP will mean that they'll be able to reduce the price even further.
Either way, all this talk about how much people from USA & Europe got their Vitas for seems a tad redundant regarding an official Japanese price drop.
