Unlikely. Haven't heard anything about it. Not that many people I know know about TWC or are interested in it (outside of this forum).
The only thing wrong with the IS2 is that Jim Cantore raises his voices weirdly when reading the wind speed in the 36 hour forecast, and sometimes, there's no text on the 36 hour forecast. Other than that, it's pretty good.
And for those of you who use emulators, the IS2 background moves, which will make it harder to emulate.
