If you are talking about first party R2 Japanese games I think all of them are in , err, Japanese. If you want to buy the same title but from third party say R1, R2 or R3 English version in Japan you might have to import them. If you want to buy those first party R1 English titles I believe you can get them in Japan or getting them online might be cheaper.

nak kirim boleh? hehehe... 

.....And 4.11 still don't fix the problem with headset.

The 4.10 updated introduced mic monitoring feature to the headset. Now you can actually hear your voice during chat (so you know when you're actually shouting to the mic). But the feature brought 2 problems. No noise filter (you can hear your wife's voice in the kitchen) and you cannot turn off the mic. The only way you can turn off the mic currently is by disabling it via XMB.
