Seems like a threat from Alstom to me - "buy our trains or we will close".
The 2.0 upgrade does however sound good, although about 150 3 car sets too late, problems/inadequatness was known in the 1.0 very early on. Replacing the Comeng is needed, but as a former suburban traveller, as far as the newer trains were concerned the Siemens was miles ahead in both quality and comfort over the Xtrapolis.
It is interesting that the likes of SSR and EDI seem to have no poblem with work for both BG and SG but Alstom only have the Xtrapolis. Then again, the former two are known for providing quality service/ products, whereas Alstom are known for their inferior quality /products.
