The wondering came over the weekend regarding the possibility that TS4 is the off line element that will run concurrently with online TS5. The reasoning being:
Statements from EA land that TS4 will be around 'for a long, long time'
The increasing probability, from such info as we have, that TS5 will be multi-player online
Recent updates/patches seem to be attempting to address some of our long standing issues & complaints
TS4 serving as the offline element = ZERO development cost/effort regarding putting an offline component into TS5
The single player crowd is pacified and the online multi crowd get what they want with no compromise
Should the online venture explode in EA's face, again, there will be no need for a mad scramble to come up with something viable (as with TS4 originally) as the bacon saver will already be in place.
Just a thought/wondering, not even up to speculation level, but worth putting out for consideration.
