For us, this news is too little, too late. Since purchasing two 41000 chassis and SGMs nearly 3 years ago, we've had so many significant issues that we've seriously considered leaving Check Point as a vendor and platform. The number of instabilities, bugs, and unexplainable issues that both TAC and Israel's R&D are unable to answer for us are really astonishing. Much of this instability has been from the custom "SP" code train that the 41000/61000 platform has run in the past. Perhaps it will be better with R80.x? Who can know... I suppose time will tell.
Internal Check Point resources have explained to me, off the record, that Check Point produced the 41000/61000 platforms originally with a broad install base in mind. Unfortunately, the platform didn't take off like they had hoped. At the end of the day, Check Point's revenue and bottom line are what drive engineering, so efforts were redirected away from the high-end chassis and toward other platforms that promised a greater return on their investments, both in time and money. This meant that issues that went all the way up to R&D were of much lower priority than others. Ultimately, this led to a sense of inaction, non-urgency, and general indifference to our issues from R&D. (TAC, on the other hand, did as best as they could, but the trouble oftentimes has been a profound lack of awareness on how to troubleshoot and understand the 41000/61000 platform. Couple this with a marginal focus from R&D and you have a platform that is both poorly supported and, frankly, a dead-end for non-carrier customers.) My understanding as well is that Check Point is quietly focusing on carriers for selling new chassis solutions and less toward the general enterprise customer.
Again, this perspective is my own only based on my own experience and from conversations I've had with internal Check Point resources. Your mileage may vary, but ours has been astonishingly poor.
I would strongly urge you NOT to consider the chassis platforms and stick with, instead, the higher-end appliances like the 23800/23900s. Their throughput is comparable nowadays anyway to what the 41000/61000 platforms can do.
Best of luck to you, either way.
