That was true for 2007; they didn't think they had time to get everything done, so they said they were holding off until this spring.
From what I was told in April (not by the team, FWIW): When they did the math, the cost of relocating the pressbox (with all the electronic/wifi access work needed), plus losing that tier of the M&T Bank Club, was enough that they'd barely break even on the new premium seats. And yeah, I don't think they're keen on putting any of their own money into the stadium right now. Can't confirm any of it yet -- I haven't been in the stadium since the season ended -- but I trust this source.
Of course, the beat guys were never told about the plan to begin with; word has it that they only found out about the proposed move when it showed up in a City/Region story in the BN.
