Critical Gamer Writes: Sony are courting a lot of controversy with their new console PSP Go. This is mainly due to the fact it's a download only device, with no UMD drive as per the older PSP models. The price of £250 is also causing a stir, with the PSP 3000 retailing for £100 less than the new model. Retailers are up in arms as well, because they'll only make money from the sale of the console, with no added games sales at launch or in the future. So where does this leave this brave new venture from Sony and what are the implications for the future?
