We love days like today, when Nintendo springs upcoming release dates on us and we all have to think of how far we're going to have to dig into our pockets for some cash.

You'll have to update your purchase plans - again - as Brain Age: Concentration Training (also known as Dr Kawashima's Devilish Brain Training: Can You Stay Focused? in Europe) and Sonic & All-Stars Racing Transformed have both been given launch dates for the US.

Brain Age: Concentration Training will mind-boggle its way onto 3DS on 10th February, while Sonic & All-Stars Racing Transformed will speed onto the handheld two days later on 12th February.

Will you be testing your brain skills in the latest addition to the Brain Age series, or will you race it out with friends to the top of the podium with Sonic and co.? Let us know!
