I am still looking forward to 4 more Classic packs, but another 1.5 million bits seems to be a little daunting.  It was relatively expensive (IMHO), but I bought the 2500 bits for the 26 card packs (so far) and the card back. 

I think if the community reaches the 25 million checkpoint to unlock those 4 classic packs, then the purchase may be worth it for the 30 card packs and the card back.
