This thread is blowing up! Great news and the design is quite modern and much less conservative than the original Comcast Center. A few observations:
- While I don't doubt that the City government will make the necessary allowances, it's still very annoying that - at this location - a height variance is still needed.
- It will also be interesting to see the NIMBY reaction. Dare they attempt to sabotage the biggest private development in the history of PA and the potential for thousands of jobs because their views will be blocked, shadows, traffic, etc.? My gut feeling is that this is way too big and concrete (unlike the ACC) for them to whine about it - they will end up looking like clowns.
- The speculation about the 4 Seasons was right all along. With that location - on the top floors of the tower - they can re-stake their claim as the premier hotel in Philadelphia.
- Also, what will happen to the current 4 Seasons. Does the recently closed Best Western take it over?

In all seriousness, a peruse on TripAdvisor show that the space would be well served by a 3-4 star hotel. Recent reviews reveal that the rooms are dated and not up to 5-star par.
- Related to the two previous bullets, how does this impact other hotel proposals, notably Element/W?
- Who will create a thread for this tower? And will it be called the Comcast Innovation and Technology Center? Maybe Comcast IT for short?
EDIT, a few more:
- Since the hotel will be on the top floors, I guess that the executives will remain in the original tower?
- In the nighttime rendering above, it does almost appear that the two towers are twins - the IT tower just has the spire.
