According to Siliconera, 65% of PSVita pre-orders last week have been for he 3G model and 82% of all pre-orders also decided on a 32GB memory card. It Will be interesting to see what the trend of pre-orders will be like in the UK, my prediction is most people will chose the non 3G version due to pricing.
Software pre-orders have not been so clever, with an average of 0.57 sales per unit. It is still early, and maybe people will pick up software when they actually get the unit.
The PSVita will officially launch in Japan on the 17th December. Still no news on a UK or American release date for the PSVita, all we know is its sometime next year.
