I think it's extremely intelligent that they're being hesitant and finishing their education. This industry is just too shaky without having something solid to fall on. These guys are talented enough to not need to venture out too far and remain popular anyway.
I fully agree with you, but perhaps the album should have been released around a time they could tour behind it. To release a record in November and not tour behind it until the summer is a shame (not saying they have any other choice.) But I'm sure they'll be alright. Seems they have a strong and growing fanbase.
