When is the Nintendo DSi coming out to the UK

i want a Dsi for my birthday (April 26th)
on most websites including the Nintendo website says that it is coming out in Spring (April to June)  
there is going to be two coloured Dsi (black and white) and there is a cam at the front and inside, 3 coloured lights on the inside, power button on the inside and the mic. in the same place. the Dsi is slightly larger than the Ds lite and the same sized SD cards are used.    i hope my information was useful!
