>The popularity of this notion stems from three facts: 1) GTCB is Genzyme's baby historically... 2) Suitable geographic location... 3) Genzyme is known to be opportunistic in such matters...<
I would add a fourth reason: People like you imagine that they are being astute for “recognizing” the high likelihood of a GENZ takeover in the event that things go well for GTC.
I think a better question is: what difference does it make who buys GTC? Genzyme, Baxter, Novartis, or American Express... what difference does it make? GENZ would not necessarily get a better price than Caterpillar, for example...
