It's a big release week, buoyed by the addition of a Good Friday — giving games an additional day to sell.

The big releases include: Portal 2, Mortal Kombat and SOCOM 4. We suspect SOCOM's going to struggle to chart, though sales should be solid amongst those that enjoyed the pre-release beta. The big battle's going to be between Mortal Kombat and Portal 2. We expect both to have promising performances at retail, but assume Portal 2 will come out on top. It's going to be close though. What's also going to be interesting is how well the PlayStation 3 SKUs of both games perform. Both boast additional PlayStation features. Portal 2 will probably edge things out on XBOX 360, but we imagine Mortal Kombat sales will lie heavily in the PS3's favour.
