Hmm, i see. (also considering other answers)

It think from a marketing perspective, it's better to have not perfect but superior product. So, even 50 oder 100 TPS would suffice to stand out.

After we fixed the whole community with that little drug, we can progress further to 250 TPS (NXT2) and in the long run with 1000 TPS (NXT3).

Think this is much more efficient because anybody will 1) see NXT is the better product and 2) it's getting better and better.
