Judgement Day sees all four Welsh regions disembark at the capital for two East v West derbies in one action packed day of rugby. With Newport-Gwent Dragons kicking things off against the Scarlets before Cardiff Blues take on the Ospreys. The stage is set and repercussions are huge.
The Dragons go into the weekend 10 points adrift of the Blues with hopes of a Heineken Cup place on their minds.
Meanwhile, the bitterest of West Wales rivals, Scarlets and Ospreys, can hardly be separated. Both teams sit on 54 points with the Swansea based Ospreys' superior points difference placing them in a playoff spot whilst their Llanelli based rivals sit only one place outside.
The WRU should be roundly applauded for an excellent concept, following the lead of the Aviva Premiership, not to mention the Super League in the 13 man code who used the same stadium for their Millennium Magic weekend.
The event is not without flaws. With many feeling the pinch of an ever tightening belt, the £25 ticket is a little steep when trying to bring 'new' fans through the gate.
However, the much lauded London Double Header has only breached 70,000 once in an 82,000 seater stadium and has seen as many 30,000 attendances as 60,000 ones.
Come This weekend all flaws, perceived errors or worries should be put aside for what will hopefully become a permanent highlight of the Welsh rugby calendar and an important day in the future of the Welsh regions.
If the rugby is half as entertaining as the setup then we may be in for one hell of a show, maybe even enough to reignite those fireworks.
