The thing is though that if it is released 5 years after the Wii U then that's generally been around the normal length for a console cycle, it's just that the PS3/360 one was much longer.
It's hard to get excited about it though. A) It's another Nintendo home console, which have been a disappointment since the Wii launched and B) all they've said is that they're working on something new. Realistically I can't imagine we'll hear anything about it until E3 next year at the earliest and a 2017 release at best.
Having said that, if I could get a Wii U for £100 I'd definitely get one! Happs, yours is gathering dust isn't it?
