Why don't you (JetBrains) do what you did with V1.5 ? Anyone who buys R# 2.5
now should qualify for free upgrade to v3 in the future. Otherwise people
will wait for v3 and in the meantime might find something else, or might
find that they can live without it.
As for not supporting VS testing in R#, I think you are making a mistake. VS
testing is a prime area where devs can clearly see that if they buy R# they
can immediately save money (by not having to buy VSTS). Considering what you
have already done with R#, VS testing support can't be that difficult. For
people like me who use VSTS at work but can't afford to have it at home,
this would be the #1 reason I'd pay for a R# upgrade.
