I can't believe I haven't heard anything about this yet beyond speculation. I just happened to be browsing the Santa Cruz website, and noticed a third choice under Blur. It's coming! A 5" travel VPP from Santa Cruz. Expected June 1.

I'm stoked because I'm hoping to buy a a good trail bike this summer and this is one more option. I'd already looked at the Intense 5.5, but I've had a sense that the SC bikes are slightly beefier.
Probably old news, but I hadn't seen it before.
