He talks about the 5 hybrid on the ping podcast with shane bacon and marty jertson (highly recommend this pod).  He is naturally a low ball hitter so the numbers he was looking for weren't happening with his 4 iron. They talked him into the 5 hyrbid to replace it now he loves it.  Its not set up like a typical hybrid though as the shaft is 98 g and 39" iirc
 
In my experience: If your miss is slightly out of the heel mb's can be every bit or even slightly more forging than a cb.  I played blades for 25 years and every time I tested irons there would be almost no difference between the blade version and the cb version of an iron.  Once I got into more game improvement type or players distance type irons my dispersion actually got wider both east to west and north to south.  
My .02: Honestly I think the reason more players use cb's now is because they not only want a tad bit more forgiveness but they simply grew up playing them.  The best iron players still overwhelmingly use blades or blade like minimal cb types.  Clubs like the callaway TCB are so marginally more forgiving than the mb that its really more mental than physical. Some robot tests have even concluded that blades are more consistent off the slight heel miss than any other iron and its most likely due to having more mass located towards the hosel iirc (in fact some have a sweet spot that looks like an elongated egg shaded towards the heel). There is also a level of focus and accountability that goes into hitting a blade when you know you need to strike it well, you adapt to miss hit the ball less.  Many competitive golfers have found they got lazy with their ball striking over time playing more forgiving clubs.  That being said i've given up on blades myself as i'm getting old and don't strike the ball as consistently as I once did. :)
