Sony has told Eurogamer that the SingStar Dance Party Pack won't be released in Europe - it's a US-only deal.
The Party Pack bundles two SingStar microphones, a USB SingStar converter and a copy of SingStar Dance for $39.99. That's the same price you pay for a stand-alone edition of StingStar Dance.
The SingStar Dance Party Pack was detailed on the US PlayStation blog.
SingStar Dance brings with it a raft of new songs as well as PlayStation Move support. The clue's in the title; you'll be dancing.
SingStar Dance arrives here on 5th November.
