Semi-related note: The NY Rangers are on life-support. My guess (and wishful) thinking is that they're waiting for the surprising bubble team to officially be eliminated from NHL playoff contention. In other words, Lantern7 mentioned that possibility (and I've noticed myself) so that Play-By-Play at MSG would become available early enough for the first time in four years (coincidentally, it was May 10, 2005). However, if the organizers needed to get that going, and New York was still in the hunt, then no PBP.
Having said that, it'll be any moment before that possibility is shot down, which means back to Stitch, but that's likely not the reason why anything hasn't been said about TARCON. Anyway, as mentioned, the info typically surfaces around a month before the event. I'd say give it a week or two (since this time 5 weeks from now people will be back home from New York). Until then, back to my busy life, and more important, immediate things that I've fallen behind on and need to play catch-up on!
