Just spotted on that linked page that T-r-U are listing the PS4 release date as a rather specific 13th December 2013? That's a Friday too, which could potentially make that a feasible launch day for the UK market...
Always been a bit wary of using Toys R Us, pretty sure they have shafted a few people in the past when there was a huge demand for new consoles by forcing bundles with their own choice of games. iirc, someone's girlfriend on here got the job of calling all of the Wii pre-orders to explain that they needed to buy about 4 shovelware games to get the console.
dont know if this has been posted before but toys r us is currently taking pre-orders for 339. hopefully we see the price fall closer to £299.
