It may be too late but Zavvi.com has the updated version of weapons brawler Blazblue with Blazblue: Continuum Shift on pre-order £17.99. Be sure to check the link below and get your pre-orders in as they will have to honour the price if your order has already been placed.
Blazblue: Continuum Shift Zavvi pre-order
UPDATE: Looks like the price has gone back up unfortunately.
On the upside, looks like you can pick up Blazblue: Calamity Trigger for cheap in their Monday deal of the day if you're quick for no more than £10.00.
Most certainly a bargain given the quality of the title, a genuine breath of frash air to the fighting genre.
