Sorry, I've just posted a similar threat in the Sales section.
Anyway, desperate? I don't think so! Yes they will be wanting to get more PSP sales under their belts, but 22m WW doesn't scream of desperation to me. Personally I reckon they have sat down and started thinking about the PSP again after dedicating way too much time on the PS3. It's actually a drop of £20 from the previous RRP of £149.99 and the PSP was released in the UK with a pricetag of £179.99, so it's drop of £50 making it nearly 30% cheaper since it's release.
Yes it is still £30 more than the DS, but it does look a hell of alot more affordable now though, and the platinum range of games which may be around 30 games come the start of May will be only £14.99 RRP...so likely to be around £9.99 at decent retailers.
Also, don't forget that Sony are only reducing the RRP to £129.99 That doesn't mean that the cheapest PSP you can buy will be £130. Amazon is selling them for £135 at the moment anyway, so we could see them on Amazon and play for around £110-£120.
Actually looking at the Platinum range, there is quite a few gems in there.
Ridge Racer, Wipeout Pure, Daxter, Lumines, Tekken Resurrection, Killzone, Locoroco
Not bad if you consider for £150 you could end up with a brand new PSP and 3 games.
