No surprising at all. And unless the already modest sales projections of SCE are significantly above actual sales, there won't be any price cuts in the near future.
You get exactly what you pay for currently at $250. It's more than most smartphones on the market from a hardware perspective (with a discounted price tied to a 2 year contract), but with the obvious omission of the basic service consumers buy a smartphone and a 2 year contract that can total about $2,000 between a $200 phone and a $75 a month bill: a telephone.
The PSV on the other hand, is first and foremost a gaming portable. Yes, it has a ton of other features with a lot of overlap over a smartphone, but consumers are looking a the PSV as a gaming platform first. And just like the 3DS at $250, the current library simply doesn't justify the cost to most, regardless of what you're actually getting for your $250, even if it is a hell of a lot more than you did for the 3DS at launch.
Comparisons to the 3DS aren't entirely valid as the 3DS was a lot less hardware (about $100 worth from a BoM perspective) with a worse launch line up that for all intents an purposes stayed stagnant until Nintendo started releasing proper titles from proven hardware selling IPs.
Until the PSV has it's equivalent of Mario Kart and Smash Bros, and Mario Land, etc. even if SCE dropped the base price to $199, all that would accomplish is giving consumers another $50 off the price of the hardware (already discounted or barely breaking even under SCE's current PSV BoM) without actually selling any more software.
And on a side note, $50 for 3G hardware is cheap when compared to the $129 Apple charges for the 3G modem in the iPad 2. Naturally, 3G data service on said devices is going to have a far more limited market since most users are presumably already paying for a data plan with their smartphone, but manufacturers still offer the option in non smartphone devices for a reason. Not everyone has a smartphone for starters.
The only problem with the PSV is that reason or whatever reasons SCE had really isn't evident. At all. The best I could offer is it's a decent anywhere web browser, gives you browser based e-mail access, and PSN message/trophy/Near data access. All better managed on a smartphone. The games themselves don't support any feature other than leader boards, which really don't merit a paid data plan one bit.
